     TECHNICAL FIELD 
     The present disclosure relates generally to computing systems and more generally to techniques for displaying information stored in a repository system. 
     BACKGROUND 
     Repository systems can perform various functions including storing and managing information about objects (e.g., an application, a process, a service, or an endpoint) in a computing environment. The information stored in a repository system can be displayed in many different ways. In organizations that have many users accessing a repository system to view information about objects, many different roles are generally defined and assigned to the users for viewing the information. In response to a user request to view information stored in the repository system, the type of information and the manner in which that information is displayed to the user can vary based on the role(s) associated with the user when the user requests to view such information stored in the repository system. The content and the type of information viewable by a user in a role even varies between the roles defined in the repository system. 
     To display information in a repository system to different users associated with different roles, preferences are typically configured for individual users and are used to determine the information shown to the users. The preferences for a user may be managed in a profile or a persona and are used to determine criteria for displaying information stored in a repository system to the user. Each profile is administered individually to adjust the manner in which information is presented to a user with respect to that user&#39;s role. As such, a profile or a persona for each user may be have to be managed individually to control presentation of information in a repository based on the role(s) associated with the user. 
     BRIEF SUMMARY 
     The present disclosure relates generally to techniques for displaying information stored in a repository system. In certain embodiments, dynamic views are used to determine what information stored in the repository system is to be displayed to a user and the manner in which the information is to be displayed. 
     In certain embodiments, a repository system may store information for various objects and their associated metadata such as attributes of the objects. An object may correspond to an application, a process, a service, an endpoint device, a resource (e.g., a database or a data structure), a method, etc., which can exist in a computing environment. An object can include a resource (e.g., a data structure or a database) in a computing environment. Information stored in the repository system about an object can be dynamically displayed to a user based on the role associated with the user. In one embodiment, a view is dynamically determined based on a role of the user and the view is then displayed to the user. Information is displayed to the user based on the determined view and the view indicates the manner in which the information is displayed to the user. 
     In certain embodiments, the repository system can store information about objects including their attributes in various different data structures (or “entities”). An entity may include without restriction a linked list, a record, a hash table, an array, any data structure, or the like. Information about an object may be stored in one or more entities within the repository. A single entity may store information about one or more objects in a computing environment. An entity may be associated with an entity type, which corresponds to one or more types of objects. A type of an object may be based on an attribute of an object, a function associated with an object, information about the object, a group to which an object belongs, or combinations thereof. The repository system can retrieve at least one entity based on an object and/or a type of object requested by a user. 
     In certain embodiments, a user may send a request to the repository system requesting information for an object or object type. In response, the repository system may configured to identify one or more entities storing information for the requested object or type of object. Information stored by the retrieved one or more entities may then be displayed to the user based on a role associated with a user. Information may be dynamically displayed by being presented in a format based on the role of the user requesting the information. The user&#39;s role (i.e., the role associated with the requesting user) determines what information from the determined one or more entities the requesting user is permitted to view. Accordingly, a right to view information stored in an entity corresponding to an object or object type may be defined based on a user&#39;s role. The right may be defined for a role with respect to an object, one or more attributes of an object, and/or a type of an object. 
     A role is thus used to determine what information in a repository system to display to a user and how to display the information. In certain embodiments, one or more viewing rights can be associated with a role. A user associated with a particular role has the viewing rights associated with that particular role. A user can be associated with one or more roles. Examples of roles may include a developer, an architect, a guest, an integrator, or a leader. In some embodiments, a user may indicate a preference for a default role when accessing the repository system. In some embodiments, a default role may be defined for the repository system and the default role may be assigned to a user (or the user may indicate a preference for the default role) when accessing the repository system. In some embodiments, a role may be associated with a user based on particular functions and/or operations performed using the repository system. 
     In some embodiments, information that can be viewed by a role associated with a user may be dynamically displayed in a particular manner (e.g., layout, arrangement, format, style, or the like) for the role. By dynamically determining, based on a user&#39;s role, a view of information in the repository system, the information displayed to a user may be displayed in a manner that is useful to the role. The view of information may improves the user&#39;s ability and visualize objects that exist in a computing environment in a manner useful to the role. A view determined dynamically based on a user&#39;s role further reduces a burden on managing profiles or personas for each individual user and enables the repository system to determine the type of information about an object that may be relevant a user associated with a particular role. 
     There are various ways in which roles may be assigned to users. In one embodiment, assignments may be done by a system administrator of the repository system or of the computing environment of which the repository system is a part. In some embodiments, a role may be assigned to a user based on particular functions and/or operations performed using the repository system. 
     In some embodiments, a role associated with a user not only determines what information the user is permitted to view but also determines the manner in which the information is displayed to the user. For example, a role associated with a requesting user may determine the layout, arrangement, format, style, etc. used for displaying the information to the user. 
     By determining, based on a user&#39;s role, a view of information in the repository system, the information displayed to a user may be displayed in a manner that is useful to the role. The view of information may improves the user&#39;s ability and visualize objects that exist in a computing environment in a manner useful to the role. A view determined dynamically based on a user&#39;s role further reduces a burden on managing profiles or personas for each individual user and enables the repository system to determine the type of information about an object that may be relevant a user associated with a particular role. 
     In certain embodiments, a repository system may use one or more view definition records to dynamically determine a view to display to a user. A view definition record can be associated with one or more different roles for accessing the repository system. A view definition record may indicate the types of objects and/or the information about an object that can be displayed to a user associated with a role. A view definition record can identify a layout for displaying, to a user associated with one or more roles, information in an entity corresponding to an object. A view definition record can identify functions and/or operations that can be performed by the one or more roles with respect to the entity. 
     In certain embodiments, a view definition record can indicate one or more related types of entities for which information can be displayed to a user associated with a particular role. A type of an entity may correspond to a type of object. The view definition record can be dynamically customized by a user with a particular role, e.g., an administrator, who has access to managing and creating a view definition record. The role may not correspond to any of the roles indicates by the view definition record. The view definition record can indicate one or more user interface formats for displaying information in an entity to a user having a role associated with the view definition record. This is different from conventional techniques in which the information to be displayed to a user has to be determined upon the individual user&#39;s profile, which can vary from user to user. The user interface format (e.g., user interface layouts and/or user interface components) used to determine a manner by which to present information to a user may enable information to be presented in a similar format to users associated with a particular role. 
     Some embodiments can perform one or more techniques for dynamically determining a view to display about information corresponding to an object in a computing environment. One such technique can be a method, which can be performed by a computing system or a computing device. The computing system or the computing device may implement a repository system or may be associated with a repository system. The method includes retrieving from a repository system, an entity corresponding to an object. The object may be indicated in a request by a user to display information about the object. The method includes determining a type of object associated with the object. In some embodiments, the method may include retrieving a plurality of entities corresponding to a type of object. The type of object may be indicated in a request by a user to display information about one or more objects associated with the type of object. The method includes determining a role associated with the user. The method includes identifying, based on the type of object, a view definition record. The view definition record may indicate a type of information to display from an entity based on the type of object. The view definition record may identify a user interface format for displaying the type of information to a particular role. The method includes determining, based on the view definition record, whether the determined role matches the particular role. The method includes, upon determining that the determined role matches the particular role, retrieving the identified user interface format. In some embodiments, the method includes retrieving criteria from the identified view definition record. The criteria may indicate the type of information to display from an entity for the type of object. In some embodiments, the method includes identifying information to display from an entity of the plurality of entities. The information may be identified based on the criteria. The method includes retrieving the identified user interface format when the particular role matches the determined role associated with the user. The method includes generating a graphical user interface to display information corresponding to the type of information from the retrieved entity. The graphical user interface may be generated based on the retrieved user interface format. In some embodiments, the graphical user interface format is generated to display the information identified from an entity of the plurality of entities. The method includes displaying the generated graphical user interface. In some embodiments, the method includes upon determining that the determined role of the user does not match the particular role: identifying, based on the type of object, a default view definition record, where the default view definition record indicates a default type of information to display from an entity based on the type of object, and where the default view definition record identifies a default user interface format for displaying the default type of information; retrieving the identified default user interface format; and generating a graphical user interface to display information corresponding to the default type of information from the retrieved entity, where the graphical interface is generated based on the retrieved default user interface format. 
     In certain embodiments, the method performed by the computing system further includes retrieving criteria from the identified view definition record, where the criteria indicates the type of information to display from an entity for the type of object. 
     In certain embodiments, the method performed by the computing system further includes retrieving an additional user interface format identified based on information in an additional view definition record associated with an additional type of object. The additional type of object may be associated with the object. The additional type of object may be different from the type of object. The graphical user interface may be generated to display the information included in an additional entity corresponding to the object. The object may be associated with the additional type of object. The graphical user interface may be generated using the retrieved user interface format and the retrieved additional user interface format. 
     In certain embodiments, the method performed by the computing system further includes determining, using the identified view definition record, a relationship between the additional type of object and the type of object and identifying the additional view definition record based on the relationship between the additional type of object and the type of object. 
     In certain embodiments, the method performed by the computing system further includes receiving information indicating a change in the role of the user to a new role, determining that the new role associated with the user does not match the particular role, and updating the generated graphical user interface to display information corresponding to the type of information from the retrieved entity. The generated graphical user interface may be updated using a new user interface format. 
     In certain embodiments, the method performed by the computing system further includes identifying, based on the type of object, a new view definition record to display information from the retrieved entity to the new role and retrieving the new user interface format identified by the new view definition record. 
     The following detailed description together with the accompanying drawings will provide a better understanding of the nature and advantages of embodiments of the present invention.

     DETAILED DESCRIPTION 
     In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of embodiments of the invention. However, it will be apparent that various embodiments may be practiced without these specific details. The figures and description are not intended to be restrictive. 
     Systems depicted in some of the figures may be provided in various configurations. In some embodiments, the systems may be configured as a distributed system where one or more components of the system are distributed across one or more networks in a cloud computing system. 
     The present disclosure relates generally to techniques for displaying information stored in a repository system. In certain embodiments, dynamic views are used to determine what information stored in the repository system is to be displayed to a user and the manner in which the information is to be displayed. 
     In certain embodiments, a repository system may store information for various objects and their associated metadata such as attributes of the objects. An object may correspond to an application, a process, a service (e.g., a composite service), an endpoint device (e.g., a terminal computer), a resource (e.g., a database or a data structure), a method, etc., which can exist in a computing environment. An object can include a resource (e.g., a data structure or a database) in a computing environment. Information stored in the repository system about an object can be dynamically displayed to a user based on the role associated with the user. In one embodiment, a view is dynamically determined based on a role of the user and the view is then displayed to the user. Information is displayed to the user based on the determined view and the view indicates the manner in which the information is displayed to the user. 
     In certain embodiments, the repository system can store information about objects including their attributes in various different data structures (or “entities”). An entity may include without restriction a linked list, a record, a hash table, an array, any data structure, or the like. Information about an object may be stored in one or more entities within the repository. A single entity may store information about one or more objects in a computing environment. An entity may be associated with an entity type, which corresponds to one or more types of objects. A type of an object may be based on an attribute of an object, a function associated with an object, information about the object, a group to which an object belongs, or combinations thereof. The repository system can retrieve at least one entity based on an object and/or a type of object requested by a user. 
     In certain embodiments, a user may send a request to the repository system requesting information for an object or object type. In response, the repository system may be configured to identify one or more entities storing information for the requested object or type of object. Information stored by the retrieved one or more entities may then be displayed to the user based on a role associated with a user. Information may be dynamically displayed by being presented in a format based on the role of the user requesting the information. The user&#39;s role (i.e., the role associated with the requesting user) determines what information from the determined one or more entities the requesting user is permitted to view. Accordingly, a right to view information stored in an entity corresponding to an object or object type may be defined based on a user&#39;s role. The right may be defined for a role with respect to an object, one or more attributes of an object, and/or a type of an object. 
     A role is thus used to determine what information in a repository system to display to a user and how to display the information. In certain embodiments, one or more viewing rights can be associated with a role. A user associated with a particular role has the viewing rights associated with that particular role. A user can be associated with one or more roles. Examples of roles may include a developer, an architect, a guest, an integrator, or a leader. In some embodiments, a user may indicate a preference for a default role when accessing the repository system. In some embodiments, a default role may be defined for the repository system and the default role may be assigned to a user (or the user may indicate a preference for the default role) when accessing the repository system. In some embodiments, a role may be associated with a user based on particular functions and/or operations performed using the repository system. 
     In some embodiments, information that can be viewed by a role associated with a user may be dynamically displayed in a particular manner (e.g., layout, arrangement, format, style, or the like) for the role. By dynamically determining, based on a user&#39;s role, a view of information in the repository system, the information displayed to a user may be displayed in a manner that is useful to the role. The view of information may improves the user&#39;s ability and visualize objects that exist in a computing environment in a manner useful to the role. A view determined dynamically based on a user&#39;s role further reduces a burden on managing profiles or personas for each individual user and enables the repository system to determine the type of information about an object that may be relevant a user associated with a particular role. 
     There are various ways in which roles may be assigned to users. In one embodiment, assignments may be done by a system administrator of the repository system or of the computing environment of which the repository system is a part. In some embodiments, a role may be assigned to a user based on particular functions and/or operations performed using the repository system. 
     In some embodiments, a role associated with a user not only determines what information the user is permitted to view but also determines the manner in which the information is displayed to the user. For example, a role associated with a requesting user may determine the layout, arrangement, format, style, etc. used for displaying the information to the user. 
     By determining, based on a user&#39;s role, a view of information in the repository system, the information displayed to a user may be displayed in a manner that is useful to the role. The view of information may improves the user&#39;s ability and visualize objects that exist in a computing environment in a manner useful to the role. A view determined dynamically based on a user&#39;s role further reduces a burden on managing profiles or personas for each individual user and enables the repository system to determine the type of information about an object that may be relevant a user associated with a particular role. 
     In certain embodiments, a repository system may use one or more view definition records to dynamically determine a view to display to a user. A view definition record can be associated with one or more different roles for accessing the repository system. A view definition record may indicate the types of objects and/or the information about an object that can be displayed to a user associated with a role. A view definition record can identify a layout for displaying, to a user associated with one or more roles, information in an entity corresponding to an object. A view definition record can identify functions and/or operations that can be performed by the one or more roles with respect to the entity. 
     In certain embodiments, a view definition record can indicate one or more related types of entities for which information can be displayed to a user associated with a particular role. A type of an entity may correspond to a type of object. The view definition record can be dynamically customized by a user with a particular role, e.g., an administrator, who has access to managing and creating a view definition record. The role may not correspond to any of the roles indicates by the view definition record. The view definition record can indicate one or more user interface formats for displaying information in an entity to a user having a role associated with the view definition record. This is different from conventional techniques in which the information to be displayed to a user has to be determined upon the individual user&#39;s profile, which can vary from user to user. The user interface format (e.g., user interface layouts and/or user interface components) used to determine a manner by which to present information to a user may enable information to be presented in a similar format to users associated with a particular role. 
       FIG. 1  shows a computing environment  100  according to an embodiment of the present invention. It should be appreciated that various different system configurations are possible, which can be different from the computing environment  100 . The embodiment shown in  FIG. 1  is thus one example of a computing system for implementing an embodiment of the invention and is not intended to be limiting. For purposes of illustration, specific embodiments are described herein for techniques for dynamically determining a view, based on a role of a user, to display information about resources and/or objects in a computing environment. 
     The computing environment  100  can include a client system  102 , a repository system  110 , and one or more data stores. The data stores can include a view definitions store  160 , a format store  170 , and a repository store  180 . The client system  102  and the repository system  110  can be implemented in different computing systems or a single computing system. The client system  102  and the repository system  110  can communicate with each other via a communication network (not shown). Examples of communication networks can include the Internet, a mobile network, a wireless network, a cellular network, a local area network (LAN), a wide area network (WAN), other communication networks, or combinations thereof. 
     The client system  102  can include a computing system or a computing device. For example, the client system  102  can be implemented in a personal digital assistant (PDA), a tablet computer, a laptop computer, a desktop computer, a wearable computer, a pager, etc. The client system  102  can include one or more memory storage devices and one or more processors. A memory storage device can be accessible to the processor(s) and can include instructions stored thereon that, when executed by the processor(s), cause the processor(s) to implement one or more operations disclosed herein. In various embodiments, the client system  102  can be configured to execute and operate a client application such as a web browser, proprietary client applications, or the like. The client applications can be accessible or operated via one or more network(s). 
     The client system  102  can be configured to communicate one or more requests (e.g., a request  108 ) to the repository system  110 . A request can indicate at least one object or a type of object for which to display information (e.g., metadata) stored by the repository system  110 . A request can be received from a user in response to interaction with the client system  102 . The client system  102  can receive one or more responses (e.g., a response  112 ) from the repository system  110 . A response can include information about one or more objects requested by a user. The information about an object can include one or more attributes about the object. An attribute about an object can indicate information such as a location of the object in the computing environment, an identifier of the object, a type of the object, and/or a relationship to other types of objects. 
     In certain embodiments, the client system  102  can display a graphical user interface (GUI) (e.g., a GUI  106 ). A GUI can facilitate access to information from the repository system  110 . The GUI  106  can display a view  190  including one or more additional GUIs. The view  190  can enable a user to specify criteria for the request  108 , such as an object or a type of object for which information is being requested from the repository system. The view  190  can enable users to search, browse, view, or edit information managed by the repository system  110 . The information displayed in the view  190  can display information including attributes about objects stored by the repository system. 
     The responses  112  received by the client system  102  can include one or more UI elements and/or one or more GUIs to present the view  190 . In some embodiments, a response  112  can include one or more UI formats and/or UI elements, which can be used to dynamically generate the view  190 . Dynamic generation of the view  190  is described below and further with reference to  FIGS. 2, 4, 5, and 6 . The view  190  can be generated based on a role associated with the user that sends a request (e.g., the request  108 ) to the repository system  110 . The view  190  can be displayed to present information about objects stored in the repository system  110 . In certain embodiments, information about an object may be chosen to be displayed based on a role associated with a user. 
     A right to view information about an object may be defined based on a user&#39;s role. The right may be defined for a role with respect to an object, one or more attributes of an object, and/or a type of an object. A role may be a way by which to manage information corresponding to objects displayed from a repository system. One or more viewing rights can be associated with a role. A role can then be associated or assigned to a user requesting information from the repository system. A user can be assigned or associated with multiple roles. The information about the objects displayed in the view  190  can be accessible based on users associated with one or more roles enabling access to the information about an object. Examples of roles may include a developer, an architect, a guest, an integrator, a leader, an administrator, a tester, or other types of roles for accessing the repository system  110 . 
     The repository system  110  can include a computing system or a computing device. The repository system can be implemented using hardware, firmware, software, or combinations thereof. The repository system  110  can manage access to and retrieval of information stored in one or more data stores, e.g., the view definitions store  160 , the format store  170 , or the repository store  180 . In certain embodiments, the repository system  110  can be implemented with one or more computing devices, e.g., a server computer  150 , which can perform operations for the repository system  110 . 
     In certain embodiments, the server computer  150  can be configured to support deployment of different types of applications to one or more client systems (e.g., the client system  102 ) in a distributed manner. For example, the server computer  150  can support the execution of one or more applications, which can be accessed by one or more client systems, e.g., the client system  102 . The applications can be provided to the client system  102  to enable a user to operate the repository system  110 . The one or more applications can be accessed and operated via the GUI  106 . In certain embodiments, the server computer  150  can exchange communication with the client system  102  to provide the client system  102  with information about objects stored in the repository system  110 . 
     The server computer  150  can implement a repository manager  130  to manage information in the repository store  180 . The repository manager  130  can store and manage information about objects including their attributes in various different data structures  182  (or “entities”). An entity may include without restriction a linked list, a record, a hash table, an array, any data structure, or the like. Information about an object may be stored in one or more entities within the repository. A single entity may store information (e.g., attributes) about one or more objects in a computing environment. An attribute can include information such as a location of the object, an identifier of the object, a type of object, and/or a relationship to other objects or types of objects. An entity may be associated with an entity type, which corresponds to one or more types of objects. A type of an object may be based on an attribute of an object, a function associated with an object, information about the object, a group to which an object belongs, or combinations thereof. The repository system  110  can identify and retrieve an entity based on the object requested by a user. 
     In certain embodiments, the entities  182  can be managed in the repository store  180  based on a hierarchical metadata model derived from one or more formalized metadata models. The resource manager  130  can generate an entity corresponding to an object that is discovered or identified in a computing environment. In certain embodiments, the resource manager  130  can generate one or more entities  182  based on information about an object provided by a user via the client system  102 . 
     In certain embodiments, the repository manager  130  can use the repository store  180  to store other information associated with the entities  182 . For example, the repository manager  130  can store in the repository store  180  one or more data structures corresponding to an entity type. An entity type can correspond to a type of object and can store information (e.g., attributes) about the type of object. A structure of an entity can be based on one or more of the entity types. As such, an entity can store information corresponding to an entity type. The repository manager  130  can identify one or more entities for an object based on a type of the object corresponding to an entity type. 
     The repository manager  130  can process the requests  108  received from the client to obtain information about an object corresponding to an entity. The repository manager  130  can perform operations to access the repository store  180  based on the request  108 . Access to the entities  182  can be based on the role of the user sending the request  108 . The request  108  can include criteria indicating the objects for which the user is requesting information to be displayed in the view  190 . 
     The server computer  150  can include or implement a view manager  140 . The view manager  140  can generate and manage a view of information stored by the repository system  110 . The view manager  140  can dynamically determine one or more views (e.g., the view  190 ) to be displayed in the GUI  106 . The view  190  can be generated based on a view definition record  162 . The view manager  140  can store and manage one or more view definition records  162  in the view definitions store  160 . A view definition record can be a data structure, which can be without restriction a linked list, a record, a hash table, an array, any data structure, or the like. A view definition record  162  can include information to identify one or more UI formats  172  for dynamically generating the view  190  for entities having one or more entity types indicated in the request  108  from a user. In some embodiments, the view  190  can be dynamically generated by the view manager  140  and then communicated in the response  112  to the client system  102  for display in the GUI  106 . In some embodiments, the repository system  110  can include, with the response  112 , the view definition record  162  and the information about one or more entities  182  corresponding to an object requested by the user. The client system  102  can include a view manager  140  that can dynamically generate the view  190  based on the information included in the response  112 . 
     A view definition record (e.g., any one of the view definition records  162 ) can include information indicating one or more UI formats  172  for displaying information in an entities having one or more of the entity types associated with the view definition record  162 . A view definition record  162  can include a criterion, which may indicate one or more different roles permitted to view information generated for display using that view definition record  162 . In some embodiments, a different view definition record can correspond to one or more roles, which are enabled to request information for an entity type. A view definition record can indicate one or more different UI formats  172  tailored for one or more roles. In this manner, different views based on an entity type can be displayed to a user based on a role associated with a user that requests information from the repository system  110 . The repository system  110  can determine a specific UI format  172  to present users with information about an object stored in one or more entities. The format of a view definition record is described further below with reference to  FIG. 3 . In certain embodiments, one or more view definition records  162  can be generated based on information (e.g., criteria) received from a user (e.g., an administrator) or predefined criteria. For example, the criteria for a view definition record  162  can be received via a GUI, such as one or more of the GUIs described with reference to  FIGS. 8-11 . 
     The view manager  140  can manage and store one or more UI formats  172  in the format store  170 . A UI format  172  can indicate one or more other attributes for displaying information stored in the repository store  180 . A UI format  172  can include or indicate one or more UI elements or components to be displayed in a view  190  generated based on the UI format  172 . The format store  170  can store one or more UI elements and/or components of the one or more UI formats  172 . In some embodiments, the one or more UI elements/components can be identified by the view definition record  162 . The format store  170  can store one or more default UI formats that can be used to generate the view  190 . The default UI formats can be used to generate the view  190  for any type of role and/or any entity type. The view manager  140  can use a default UI format to generate the view  190  upon determining that criteria for the UI formats  172  is not satisfied for information to be displayed for a requested object. 
     The present disclosure may alleviate a burden on administrators of a repository system by determining a view of information an object based on the role of a user and the object for which information is being requested. In doing so, an administrator of a repository system may not have to manage profiles and/or personas for individual users to determine the information to display from the repository system and the manner in which to display the information. By storing records (e.g., a view definition record), which may indicate a UI format for displaying information based on a relation between a type of an object and a type of role, customization of individual profiles or personas can be reduced or eliminated. Further, a view definition record can be easily modified by an administrator to add or remove different roles that presented with a view based on the view definition record. An administrator can modify or create a view definition record to provide a view for similar entity types, such as those, which can be displayed in a similar UI format. With little effort, an administrator can update a view definition record to add or remove roles and/or entity types to accommodate for frequent changes in roles and the types of information managed by the repository system. 
       FIG. 2  shows a computing environment  200  according to one embodiment of the present invention. The computing environment  200  can include a repository system, e.g., the repository system  110 . The repository system  110  can include the server computer  150 . The repository system  110  can be coupled to the view definitions stores  160 , the format store  170 , and the repository store  180 . 
     As explained above, the repository system  110  can dynamically determine a view to display information stored by the repository system  110  based on a role of a user accessing the repository system  110 . The repository system  110  can be implemented as one or more functional blocks or modules configured to perform various operations for accessing information stored by the repository system  110 . The repository manager  130  can include a store manager  232  to manage information about objects stored in one or more entities  182  in the repository store  180 . The repository manager  130  can include a request handler  234  to manage requests received from a client system (e.g., the client system  102 ). The view manager  140  can include a user profile manager  242 , a view definition manager  244 , a view definition generator  246 , a view generator  248 , and a role manager  234 . 
     The request handler  234  can manage receiving requests (e.g., the request  108 ) from a client system. The request handler can process a request and provide information to the store manager  232  to process a request for an entity. 
     The store manager  232  can manage (e.g., create, update, or delete) information (e.g., the entities  182 ) stored in the repository store  180  about objects that are discovered or identified in a computing environment. For example, the store manager can create, update, or delete one or more entity types for one or more of the entities  182 . In certain embodiments, the entities  182  can be updated or deleted based on changes in the entities  182  themselves. In some embodiments, the store manager  232  can store information indicating relationships between the entity types. The entities  182  can be updated or deleted based on changes in the information stored in association with the entities  182 . Such information may include entity types or relationships between entity types. The store manager  232  can retrieve information in an entity based on the object and/or a type of object requested by a user. The store manager  232  can retrieve information from an entity  182  in the repository store  180 . 
     The view generator  248  can dynamically generate one or more views (e.g., the view  190 ) displayed in the GUI  106 . A view (e.g., the GUI in  FIG. 5 ) can display information about an object indicated by the request  108 . The view generator  248  can generate a view of information for an object based on one or more view definition records  162  identified based on the object or the type of object requested by a user. The view generator  248  can generate the view for the object based on a view definition record that indicates a role of the user making the request  108 . For an entity corresponding to a requested object, the view generator  248  can generate the view of information permitted for the role based on a criterion in the identified view definition record. 
     The role manager  234  can manage rights of a user associated with a role to view information stored by the repository system  110 . For example, the role manager  234  can determine whether a user, based on a role associated with the user, has access to view information about an object stored in the repository system  110 . The role manager  234  can determine the information about an object that can be viewed. In certain embodiments, a view definition record  162  may include a criterion that indicates one or more roles, which can view the information. In some embodiments, a view definition record  162  may indicate particular attributes that can be viewed by a role. Based on the criterion, the role manager  234  can determine whether a role associated with a user matches a role indicated by the criterion in the view definition record  162 . 
     The user profile manager  242  can manage one or more profiles corresponding to one or more roles for viewing information in the repository system  110 . A profile can indicate one or more roles for viewing information in the repository system  110 . In some embodiments, a profile can indicate attributes for using the repository system  110 . The user profile manager  242  can determine a role of the user based on a profile associated with the user. In some embodiments, each role can correspond to a user profile defined for that role. 
     In some embodiments, a view can include one or more of the GUIs (e.g., the GUIs in  FIGS. 8-11 ) that enable a user (e.g., an administrator) to create, update, and/or delete a view definition record  162 . In some embodiments, a view can includes a repository preferences GUI (e.g., the GUI in  FIG. 7 ) to enable a user to select a profile corresponding to a role for operating the repository system  110 . The selected profile may be used to determine the role of a user operating the repository system  110 . 
     The view generator  248  can process one of the view definition records  162  to determine one or more UI formats  172  for displaying information in an entity corresponding to a requested object. In some embodiments, a UI format can be determined based on one or more data structures identified in a view definition record  162 . In specific embodiments, a view definition record  162  can indicate one or more regions to present in a view of information corresponding to one or more entity types indicated in the view definition record  162 . Each region can correspond to a task flow, which can indicate a set of activities that can be performed for the entity types displayed for the region. In some embodiments, the view definition record  162  can indicate one or more UI layouts to display information in each entity that are related to a requested entity type. 
     Based on the regions and associated layouts included on those regions, the view generator  248  can generate a view model used to generate a graphical user interface to display information about an object. A view model can provide a mapping that defines a UI format, which can be used to dynamically generate a view of information. The structure and format of a view definition record  162  is described below with reference to  FIG. 3 . In certain embodiments, determination of the view model and the mapping of the view model to a UI format are described with reference to  FIGS. 4 and 5 . In certain embodiments, the view generator  248  can generate all or a portion of the view  190  to be displayed by the GUI  106 . One of ordinary skill in the art may appreciate that performance for generating the view  190  may be enhanced by generating all or a portion of the view at the client system  102 . 
     In some embodiments, the view generator  248  can determine the UI elements and/or components to include in the view based on a selected one of the view definition records  162 . The view definition record can indicate locations to UI elements (e.g., a widget, a control, a button, an input field, etc.) to be included in the dynamic view. The locations can correspond to one or more locations in a data store (e.g., the format store  170 ) that can contain UI elements. The UI elements in the data store can include locations of UI artifacts (e.g., a wrapper task flow, a page definition file, and/or a page fragment). The view definition record  162  can indicate the locations (e.g., a region) within a UI format to display the UI elements. In some embodiments, the UI elements in the selected view definition record can correspond to the functions associated with the region. 
     The view definition generator  246  can generate a view definition record  162  based on one or more criteria provided by a user through one or more GUIs (e.g., the GUIs in  FIGS. 8-11 ). A criterion can indicate an attribute to be associated with a view. An attribute can be used to determine information in an entity that can be displayed. A criterion can indicate one or more entity types and/or one or more entities accessible to a user presented with a view displayed based on the view definition record  162 . Information can be displayed based on the view definition record  162  for an entity that satisfies the criterion. In some embodiments, a criterion can indicate one or more roles that can access information displayed based on the entities that can be viewed according to the view definition record  162 . A view definition record  162  can be generated in a format as described with reference to  FIG. 3 . 
     In some embodiments, a default view definition record can be created for one or more attributes that are chosen by default for a user having a particular role (e.g., a default role). The default view definition record can be used to display information included in an entity when no view definition record exists for displaying information in the entity. In some embodiments, the default view definition record can be created for a role (e.g., a default role) that a user can be assigned by default when accessing the repository system. 
     The view definition manager  244  can manage access to configure (e.g., create, read, update, and delete) one or more of the view definition records  162 . In some embodiments, the view definition manager  244  can permit access to create, read, update, and/or delete one or more view definition records  162  based on a role of the user of the repository system  110 . For example, the view definition manager  244  can permit an administrator to create and update view definition records  162 . In such embodiments, certain roles may be permitted to prevent unauthorized users from creating, modifying, or deleting view definition records. In some embodiments, the view definition manager  244  may obtain information determined by the role manager  234  with respect to information in a view definition record  162  that can be accessed by a role associated with a user. 
     The view definition manager  244  can manage access to information stored in the view definition records  162 . Upon receiving a request (e.g., the request  108 ) from a user, the view definition manager  244  can identify and retrieve view definition records  162 . The view definition manager  244  can search the view definitions store  160  to identify a view definition record that is associated with an entity corresponding to an object requested by a user. The view definition manager  244  can analyze attributes and/or criterion in the view definition records in any order or any manner. The criterion may be analyzed to determine attributes about an object that can be displayed to a user associated with a role. 
       FIG. 3  shows a view definition record  300  according to an embodiment of the present invention. The view definition record  300  can be generated and managed by a repository system, e.g., the repository system  110  of  FIG. 1 . As explained above, a view definition record  300  can include information to indicate a UI format for dynamically generating a view (e.g., the view  190 ) of one or more entities having one or more entity types  304 . The view definition record  300  can include information indicating a UI format for displaying entities having one or more of the entity types  304 . The view definition record  300  can be generated based on information (e.g., at least one criterion) received from a user or at least one predefined criterion. In certain embodiments, the information to generate a view definition record can be received via one or more of the GUIs described with reference to  FIGS. 8-10 . The view definition record  300  and the UI components identified based on the view definition record  300  can be generated by the client system  102  and/or the repository system  110 . 
     The view definition record  300  can include a view definition  302 . The view definition  302  (e.g., a data structure or a flat file) can include general information about a dynamic view that can be generated based on the view definition record  300 . The general information can include information displayed in a main UI of the dynamic view. The view definition  302  can include information used to determine how to generate the dynamic view. The view definition  302  can include at least one attribute and/or at least one criterion indicating one or more entities from which information can be displayed in a dynamic view (e.g., the view  190 ) based on the view definition record  300 . The view definition  302  can include information identifying a name  310  and/or a description  312  for the dynamic view generated based on the view definition record  300 . A dynamic view can be generated based on the view definition record  300  for entities that are associated with one or more of the entity types  304 . In some embodiments, information in different entities having the same entity type may be dynamically displayed in different views, such that information corresponding to certain entities having entity types  304  can be displayed based on the view definition record  300 . 
     The view definition  302  can include target criteria  308 , which can provide one or more additional criterion to determine entities based on which information can be displayed using the view definition record  300 . For example, entities such as a Web Services (WS) Service and a Representational State Transfer (REST) Service can have the same entity type; however, information in one of these entities can be displayed based on the view definition record  300  for the entity that satisfies the target criteria  308 . In some embodiments, the target criteria  308  can include criteria in a query language, such as a Java Persistence Query Language (JPQL). The entity type  304  along with the target criteria can be used to determine which entities can be displayed based on the view definition record  300 . 
     The view definition record  300  can include one or more UI formats (e.g., the UI format  172 ) which can be used to generate the dynamic view (e.g., the view  190 ) for information corresponding to an entity that satisfies the criteria of the view definition record  300 . In certain embodiments, the view definition  302  can indicate one or more UI locations  314  of UI elements (e.g., a widget, a control, a button, an input field, etc.) to be included in the dynamic view. The UI locations  314  can include one or more locations in a data store (e.g., the format store  170 ), which can contain UI elements. The UI elements in the data store can include locations of UI artifacts. A UI artifact can include one or more of any of the following: a wrapper task flow, a page definition file, and/or a page fragment. A UI format can be determined based on the UI elements stored at the UI locations  314  and one or more UI components, e.g., regions, displayed in the dynamic view. Each region can display information based on a task flow definition corresponding to a task flow. Information about the task flows can be stored in a data store (e.g., the format store  170 ). A task flow provides a modular approach for defining control flow in a GUI. The task flow can relate to a set of activities that can be performed in the GUI for entities that are presented based on the view definition record  300 . 
     The view definition record  300  can include one or more region definitions  320 . Each region definition  320  can correspond to a task flow. The region definition  320  can indicate criteria for displaying UI elements corresponding to a region of a GUI. The region definition  320  can include attributes corresponding to a UI format of the region. Generating a view dynamically from a UI format can be described further with reference to  FIGS. 4 and 5 . 
     The region definition  320  can include information that defines at least one attribute and/or at least one criterion of a region of a UI format determined based on the view definition record  300 . A region identifier  322  in the region definition  320  can indicate a region corresponding to the region definition  320 . The region definition  320  can include a description  326  of a region. The region definition  320  can include one or more UI attributes of a UI generated for a region in a dynamic view. 
     The UI attributes of the region definition  320  can include a UI layout type  324  that indicates a type of layout of a region. For example, the UI layout type  324  can indicate a function layout or a generic layout. The region definition  320  can include one or more UI layout identifiers  328  that identify a portion of a UI layout for the region corresponding to the region definition  320 . The region definition  320  can indicate one or more UI configuration files  330  that can store additional information about a UI configuration of the region. In some embodiments, the UI configuration files  330  can include one or more extended markup language (XML) configuration files that indicate UI display properties for the region. The UI display properties can indicate style, display properties, control types, list-of-values, other types of display properties, or a combination thereof. 
     The region definition  320  can include information about one or more relationship configurations  332 . The relationship configuration  332  can indicate one or more relationship configurations. A relationship configuration can be a data structure that provides information for displaying, within a region, information corresponding to entities that have the entity type(s)  304  and that satisfy the target criteria  306 . For example, the region definition  332  can identify a relationship configuration  340  and a relationship configuration  360 . Each of the relationship configurations  340 ,  360  can be represented as a node (e.g., a location or an area) within a region identified by the region definition (e.g., the region definition  320 ). 
     A relationship configuration, e.g., the relationship configuration  340 , can provide a configuration for displaying information corresponding to entities for a node of a region in a dynamic view. A relationship configuration can be defined for each node in a region. A node can be defined for each distinct type of data identified as having the entity type  304  and an associated entity type. For example, the associated entity type can include an interface, an endpoint, a deployment, or other type of resource or object that can be associated with the entity type  304  (e.g., composite). The view definition record  300  can include the relationship configuration  340  for a node corresponding to an entity type associated with the entity type  304  and the relationship configuration  360  for another node corresponding to another entity type associated with the entity type  304 . 
     In  FIG. 3 , the relationship configuration  340  can include an entity type  346  for an entity that has one of the entity types  304  and that satisfies the target criteria  306 . The entity type  346  of an entity can be associated with the entity type  304 . The relationship configuration  340  can indicate a node name  342  corresponding to a node, which is displayed in a portion of a region. The relationship configuration  340  can include a type path  344  associated with the entity type  346 . The type path  344  can indicate a path in a hierarchical data model from a root entity type to the entity type  346 . The type path  344  can be used to identify a data structure corresponding to the entity type  346  in the hierarchical data model. The data structure corresponding to the entity type  346  can provide attributes of the entity type  346 . The attributes for the entity type  346  can be used to determine what information to display about the entities having the entity type  346  and how to display the information about those entities. The relationship configuration  340  may indicate one or more UI attribute configuration files  348 . A UI attribute configuration file may indicate UI attributes for generating a UI corresponding to a node for the relationship configuration  340 . 
     The relationship configuration  340  can include attribute configuration information  350 . The attribute configuration information  350  may indicate one or more attribute configuration(s)  370 ,  380 . The attribute configuration(s)  370  can identify one or more attributes configurations  390 ,  392 . Each of the attribute configurations  370 ,  380  can be associated with a data structure. Each attribute configuration  370 ,  380  can indicate a configuration for displaying information about attributes related to the entities having an entity type (e.g., the entity type  346 ) of a relationship configuration (e.g. the relationship configuration  340 ). 
     An attribute configuration, e.g., the attribute configuration  370 , can include a name (e.g., a name  372 ) of the attribute configuration. The attribute configuration  370  can include UI display properties  374 . The UI display properties  374  can indicate information about displaying information about one or more attributes corresponding to an entity type (e.g., the entity type  346 ) of the relationship configuration (e.g., the relationship configuration  340 ). In some embodiments, the UI display properties  374  can indicate a UI configuration file (e.g., a UI configuration XML, file). The UI display properties  374  can indicate properties for displaying UI elements for presenting the attributes corresponding to the entity type. For example, the UI display properties  374  can indicate a style, display properties, control type(s), list-of-values, other types of display properties, or a combination thereof. 
     The UI display properties  374  can identify one or more UI components, such as a UI component  376 . The UI component  376  can include a UI layout  382  and/or one or more UI page components  384 . The UI layout  382  and/or the UI page components  384  can be used to generate a portion of a UI corresponding to a node identified by a relationship configuration  340 . Each of the attribute configurations  370 ,  380  can be associated with one or more other attribute configurations  390  and  392 . Each of the attribute configurations  390  and  392  can identify configurations for displaying information in each attribute (e.g., extended attributes) related to an attribute for an attribute configuration (e.g., the attribute configuration  370 ). The attributes displayed for the attribute configurations  390  and  392  can be attributes that are extended from the entity type  346 . 
     By determining a format for displaying information based on stored task flows corresponding to an entity type, the repository system can dynamically determine UI elements to display a feature and/or a function available an entity associated with the entity type. The stored task flows can indicate the type of activities and/or features for accessing the entity type. By indicating UI elements and/or attributes in a view definition record with respect to displaying information about an object corresponding to an entity having a certain entity type, a display presented based on the entity type can be customized without a need to modify individual profiles to specify display attributes for those entity types. The UI format identified based on the view definition record can enable a repository system to selectively determine the features to display information in entities to certain types of roles. Identification of the properties and UI elements for each region enable an administrator to modify a source of UI components and/elements, rather than having to modify a specific display profile. Further, a view definition record can enable the repository system to determine a layout that is most effective for certain roles when viewing entities having one or more of the entity types indicated by the view definition record. 
       FIG. 4  shows a mapping  400  of a view definition record (e.g., the view definition record  300 ) dynamically to UI format  450  of a view according to an embodiment of the present invention. A view model  410  can be used to determine the mapping  400 , which can be used to produce the UI format  450 . The dynamic UI format  450  can be generated based on a layout or organization of elements determined from the view model  410 . The UI format  450  can be used to determine the task flows that can be implemented for the UI format to generate the dynamic view. An example of the UI format  450  generated based on the mapping  400  is discussed with reference to  FIG. 5 . The mapping  400  described with reference to  FIG. 4  can be performed by the repository system  110  of  FIG. 1  or the client system  102 . 
     In certain embodiments, the view model  410  can be used to determine the UI format  450  for displaying information in one or more entities in a dynamic view (e.g., the view  190 ). The layout of the view model  410  can be generated based on the view definition record (e.g., the view definition record  300 ) for the one or more entities requested to be displayed for the dynamic view. The view model  410  can be determined based on a predetermined format that is modified based on the view definition record. In some embodiments, the view model  410  can be generated dynamically based on the view definition record. 
     The view model  410  can be associated with an identifier (e.g., UUID) corresponding to information each of the entities that can be displayed based on UI format  450  determined from the view model  450 . The view model  410  can be associated with a view name. The view name can correspond to a name associated with the view definition record. The view model  410  can indicate attributes  412  for the UI format  450 . For example, the attributes  412  (e.g., a view name or a UUID) associated with a main view in the view model  410  can be used to determine a entity view task flow  452  to be displayed in the UI format  450 . The task flow  452  of the UI format  450  can display general information from an entity in a dynamic view. For example, the general information can include information in the view definition  302  of the view definition record  300 . 
     Using the view definition record  300 , the task flow  452  can be identified and selected from a UI store (e.g., the format store  170 ) associated with the repository system. The task flow  452  can indicate a method and/or layout for displayed information in entities that have the entity type (e.g., the entity type  346 ) and that satisfy the target criteria  308  for a view definition record corresponding to the view model  410 . The view definition  302  can be used to populate the task flow  452  of the UI format  450 . The dynamic view can be generated based on the UI format  450  and the information indicated in the view definition record. 
     The view model  410  can include one or more region models  414 . Each region model  414  can correspond to a region ID. The region ID can be used to identify each region in the UI format  450 . Each region model  414  can correspond to a region definition (e.g., the region definition  320 ) of a view definition record. The UI format  450  can include one or more regions  454 . Each region  454  can be an area in the UI format  450 . The region  454  can be generated for the dynamic view based on the corresponding region definition indicated by the region model  414 . 
     The view model  410  can include one or more nodes  416 . Each node  416  can correspond to a different node indicated by the view definition record. For example, each node  416  can correspond to a node identified in a relationship configuration (e.g., the relationship configuration  340  or the relationship configuration  360 ). Each node  416  can map to a page fragment  456  within a region  454 . Each node  416  can include a node entity  418 . Each node entity  418  can correspond to a different entity in the node  416 . Each node entity  418  can include one or more entity attributes  420 . The entity attributes  420  can be used to present information for the node  418 . The entity attributes  420  can correspond to attributes indicated by an attribute configuration  370 ,  380 ,  390 ,  392  in the view definition record  300 . 
     Each region  454  can contain one or more page fragments  456 . Each page fragment  456  can correspond to a task flow of activities corresponding to the node  416 . The task flow corresponding to the page fragment can be part of a single larger task flow that for the region  454 . In some embodiments, the page fragment  456  can be a document that can be rendered as content in a page. For example, the page fragment  456  can be a Java server page (JSP) document that can be rendered as content in another JSP, e.g., a JSP of the region  454 . 
     The page fragment can be retrieved from a data store, e.g., the format store  170 . The page fragment  456  can be identified based on the attributes of the node  416  in the view model  410 . The page fragments  456  can contains one or more components to include in the UI format  450  for the node. A component can indicate a format for presentation of the node  416  in the region  454 . In some embodiments, the page fragment  456  can be identified based on one or more of the entity attributes  420  of the node  418 . 
     The resulting UI format  450  determined based on the view model  410  can be used to dynamically generate a view (e.g., the view  190 ) to display to a user in response to a request to view information about entities. The task flows  452 ,  454 , and the page fragments  456  can all be used to generate the view. Described below with reference to  FIG. 5  is an example of a dynamic view that can be generated based on the UI format  450  determined from the mapping  400 . 
     In  FIG. 5 , a dynamic view  500  of entities generated based on a view definition record (e.g., the view definition record  300 ) is shown according to an embodiment of the present invention. In certain embodiments, the view  500  can be generated based on a UI format (e.g., the UI format  450 ) determined based on a view definition record. The view  500  can be generated by the repository system  110  or the client system  102  of  FIG. 1 . The view  500  can be displayed in response to a request to access (e.g., create, read, update, or delete) one or more objects which correspond to one or more entities that are associated with one or more entity types. In the example shown in  FIG. 5 , the view  500  presents a dynamic view of an object having a composite type. The view  500  can be displayed based on criteria provided by a user to access entities associated with the composite type. The view  500  can display information in an entity such as a “BPEL process1” that has one or more of the types of objects chosen for the view  500 , such as the composite type. 
     To generate the view  500 , a view definition record (e.g., the view definition record  300 ) can be identified corresponding to the entity types requested by a user having a role for accessing the repository system. Upon identifying a view definition record, a UI format (e.g., the UI format  450 ) may be determined and used to generate the view  500 . The UI format can be determined based on a mapping, such as the mapping  400  described with reference to  FIG. 4 . 
     The view  500  can present an entity view  502  that provides information about the entity types to be displayed in the view  502 . The entity view  502  can be generated based on the entity view wrapper task flow (e.g., the entity view wrapper task flow  452 ) of a UI format (e.g., the UI format  450 ) mapped based on a view definition record associated with the entity types. The entity view  502  can include a name  504 , an entity type  506 , a status  508 , and a categorization  510 . Each of the attributes can be obtained from the view definition record  300  and/or from a view model, e.g., the view model  410 , determined based on the view definition record  300 . The name  504  of the entity view can corresponds to a view name associated with a view model (e.g., the view model  410 ). The entity type  506  can indicate one or more entity types (e.g., a “composite” entity type) that are presented in the entity view  502 . The status  508  can indicate a status of a user&#39;s access. The categorization  510  can indicate a categorization of the entity types shown in the view  500 . 
     The view  500  can include one or more regions such as  520 ,  540 ,  560 . Each of the regions  520 ,  540 ,  560  can correspond to a region (e.g., the region  454 ) in a UI format  450 . As explained above, the region in a UI format can be mapped based on a region definition (e.g., the region definition  320 ) indicated in a view definition record associated with the entities having the entity type (e.g., the entity type  506 ) presented in the view  500 . 
     Each of the regions  520 ,  540 ,  560  can display information about entities having an entity type corresponding to one or more nodes included in a region. For example, the region  520  can include one or more nodes  522 ,  524 ,  526 , each of which can have information about entities corresponding to an entity type of the corresponding node. In the region  520 , a node  522  can have entities associated with a first entity type (e.g., a service deployment), a node  524  for entities associated with a second entity type (e.g., an endpoint), and a node  526  having entities associated with a third entity type (e.g., an interface). The information from the entities displayed in the nodes can include one or more UI element for the entities. For example, the node  522  can display UI elements associated with one or more entities  528 . The UI elements associated with the entities  528  can display information about attributes of those entities  528 . 
       FIG. 6  shows a flowchart illustrating a process for dynamically displaying information in a repository system based on a role of a user according to an embodiment of the present invention. At a high level, process  600  includes a design-time portion  660  including processing performed at design time and a run-time portion  670  (or request time portion) including processing performed during runtime. Design-time  660  processing includes creating views and associating the views with roles. Design-time  660  may also include (not shown in  FIG. 6 ) assigning roles to users. Run-time  670  includes processing that is triggered upon a request by a user for information in the repository system and that determines a response to the request, such as presenting a view of the information based on the role of the user. Run-time  670  processing may include processing to dynamically display a view of information about an object associated with a type of object when requested by a user associated with a role associated with the view. 
     Beginning at block  605 , a view definition record is created to define a view for displaying information about a type of object or an object in the repository system to one or more roles. The view definition record may include at least one criterion indicating the type of information about a type of object or an object that can be displayed. A criterion may be specified in the view definition record by identifying one or more entities and/or one or more entity types in the repository system that can be viewed by a user and more specifically, the information that can be viewed from the entity or the entities satisfying the criterion. The criterion can specified with respect to one or more roles for accessing the repository system. A view definition record may be used to identify a UI format for displaying information about an object or a type of object to user with a particular role. In some embodiments, a UI format may be specified with respect to an entity type corresponding to a type of object. The view definition record can be generated as described above with references to  FIGS. 2 and 3 . 
     In one example, the process  600  can create the view definition record  300  of  FIG. 3  to include one or more criteria defining the type of object(s) corresponding to an entity type (e.g., the entity type  304 ) that can be viewed in a repository system. The view definition record  300  can include a UI format, such as the format defined based on one or more region definitions, e.g., the region definition  320 . The view definition  300  record can indicate one or more roles, such as target roles  306 , which are permitted to view information included in entities that satisfy the criteria of the view definition record  300 . 
     At block  610 , a request is received to display a view of information about an object (e.g., Composite Service A). In some embodiments, the request may include a type of object (e.g., a composite service) to indicate one or more objects in a repository system. The request can be made by a user associated with a role. The role may correspond to a role for operating or using the repository system. For example, a role may be a developer role in which the user is requesting to view attributes about a composite service stored in the repository system. 
     At block  615 , a type of object may be determined for the request. The type of object may be indicated by the request. In some embodiments, the type of object of an object may be determined by locating an entity corresponding to the object in the repository system. The type of object may be determined based on an entity type of an entity corresponding to the object. 
     At block  620 , one or more entities are retrieved from the repository system. An entity may be retrieved for an object or the type of object of an object requested by a user. 
     At block  625 , a role associated with the user may be determined. For example, a role may be determined based on information (e.g., login information) identifying a user submitting the request. In some embodiments, a user may be identified based on information identifying a client system used to submit a request. The information identifying the client system may be used to identify the user and determine the role associated with the user. The repository system may store information identifying a user in association with one or more roles for the user. 
     At block  630 , the process  600  can include identifying, based on the type of object, a view for displaying information about one or more objects associated with the type of object. For example, one or more view definition records can be identified based on the type of object. A view definition record may be identified based on an entity type corresponding to the type of object (e.g., a composite service). A view may be defined based on a view definition record. A view definition record may indicate a type of information to display (e.g., an attribute of an entity) from an entity corresponding to entity type. A view definition record may identify a format (e.g., a user interface format) for displaying the type of information corresponding to an entity. The format may be identified at a data source, which stores information about the format. In some embodiments, a view definition record may include one or more criteria for displaying information about objects associated with the type of object. For example, a criterion may indicate one or more attributes of an object that can be displayed. The criteria can be associated with a role for viewing information in the repository system. 
     At block  635 , process  600  may include determining whether a determined role associated with a user matches the particular role for which a view is identified. In some embodiments, the determined role associated with the user may be compared to the particular role indicated by a view definition record identified at block  630 . Upon determining that the determined role matches the particular role, process  600  may proceed to blocks  650  and  655  to generate the identified view of information about one or more objects requested by a user. Upon determining that the determined role does not match the particular role, process  600  may proceed to blocks  640  and  645  to generate a default view of information about one or more objects requested by a user. 
     At block  640  to retrieve a default UI format identified by a default view definition record. A default view definition record may include information to generate a default view for displaying a default type of information about one or more objects associated with a type of object. A default view definition record may be identified based on the type of object. A default view definition record may be identified based on an entity type corresponding to the type of object (e.g., a composite service). 
     A default view may be defined based on a default view definition record. A default view definition record may indicate a default type of information to display (e.g., an attribute of an entity) from an entity corresponding to entity type. A default view definition record may identify a default format (e.g., a user interface format) for displaying the type of information corresponding to an entity. The default format may be located a data source, which stores information about the format. In some embodiments, a default view definition record may include one or more criteria for displaying information about objects associated with the type of object. For example, a criterion may indicate one or more attributes of an object that can be displayed. The criteria can be associated with a default role for viewing information in the repository system. 
     At block  645 , the process  600  can generate a default GUI based on the default UI format identified by the default view. The default UI format may indicate a manner in which to display the default type of information from the retrieved entity/entities. The GUI based on the default UI format. 
     Returning to block  635 , when the determined role associated with the user matches the particular role for an identified view, at block  650 , a UI format can be retrieved for the identified view. For example, the process  600  can retrieve a UI format (e.g., the UI format  450 ) identified by a view definition record as explained above with reference to  FIGS. 3-5 . 
     At block  655 , the process  600  can generate a GUI, e.g., the GUI  500 , to display the type of information from the retrieved entity. The GUI can be generated based on the UI format retrieved at block  650 . 
     Then at block  660 , the default GUI generated at block  645  or the GUI generated at block  655  may be displayed. The process  600  can proceed to end at block  665 . 
     In certain embodiments, the process  600  can be implemented by certain embodiments of the repository system  110 . The repository system  110  can implement the process  600  to determine a UI format to display a type of information in an entity corresponding to an object or a type of object requested by a user associated with a role. In certain embodiments, block  605  can be performed during design-time portion  660  that is different from run-time portion  670  when blocks  610 - 660  can be performed. Design-time  660  and run-time  670  may occur in any order. In some embodiments, run-time  670  may occur subsequent to (e.g., immediately after) design-time  660 . For example, block  605  can be performed during the design-time  660  when one or more view definition records can be created. 
     Process  600  can be performed in an iterative manner for design-time  660 , the run-time  670 , or both. For example, block  605  can be iteratively performed during design-time  660  for each view definition record based on criteria associated with one of a plurality of roles. In another example, blocks  610 - 660  can be iteratively during run-time  670  for each request (e.g., the request  108 ) received from a user of the repository system. It will be appreciated that process  600  is illustrative and that variations and modifications are possible. Action or operations described for process  600  as sequential may be executed in parallel and/or order of operations may be varied, and operations may be modified, combined, added or omitted. 
       FIG. 7  shows a GUI  700  (e.g., a view profile interface) to receive user criteria to display a view according to an embodiment of the present invention. Specifically, the user criteria can indicate a user&#39;s selection of a role for operating the repository system according to an embodiment of the present invention. The role specified via the GUI  700  can be used to dynamically generate a view of entities having one or more entity types according to an embodiment of the present invention. The GUI  700  can be included or implemented in the GUI  106  of  FIG. 1 . The GUI  700  can be presented to a user operating a client system (e.g., the client system  102 ) to access a repository system (e.g., the repository system  110 ). 
     The GUI  700  can include one or more interactive elements, which can receive input indicating one or more preferences to operate the repository system. For example, the GUI  700  can include a repository preferences element  702  to cause the GUI  700  to display one or more interactive elements  704 ,  706  that enable the user to specify preferences for operating the repository system. The GUI  700  can include a page size element  706 , which can receive input indicating preferences for a display page size to display information accessed from the repository system. The GUI can include a profile element  704 , which can receive input indicating selection of a view profile, or a role, for operating the repository system. Input received from selection of the profile element  704  can be provided in the request  108  to the repository system  110 . The repository system can use the role to determine how to display information in an entity in response to a request, as explained above. 
       FIG. 8  shows a GUI  800  to receive criteria for a view definition record according to an embodiment of the present invention. Specifically, the GUI  800  can receive input including criteria for a view definition record, e.g., the view definition record  300 . The input received via the GUI  800  can be used to generate a view definition record. The GUI  800  can be included or implemented in the GUI  106 . The GUI  800  can enable a user (e.g., an administrator) who is permitted to access the repository system to create a view definition record.

An interactive element  814  may receive input indicating a description of the view definition record. An interactive element  812  may receive input indicating a title for the view definition record. The GUI  800  can include an interactive element  810  to receive input indicating one or more roles to be associated with a view definition record created for the criteria indicated by the GUI  800 . Interaction with the interactive element  410  may cause a different GUI (e.g., the GUI described with reference to  FIG. 9 ) to be displayed that enables a user to choose one or more roles from a list of roles identified for the repository system. 
     The GUI  800  can include one or more interactive elements to indicate criteria for determining one or more types of entities that can be viewed in a GUI for a user having a role indicated by the interactive element  810 . In some embodiments, the GUI  800  can include an interactive element  804  to receive input that indicates one or more entity types. The entity types can be used to determine the entities that can be presented to a user. In some embodiments, the GUI  800  can include an interactive element  806  to receive input that indicates target criteria for presenting entities to a user. The target criteria can be in a query language which can be used to determine entities that can be viewed by a user. As explained above, the criteria received via the GUI  800  can be used for criteria to generate a view definition record. 
     In certain embodiments, the GUI  800  can include an interactive element  808 . The interactive element  808  can receive input which indicates one or more view definition templates. A view definition template can provide criteria to create a view definition record for one or more roles for accessing a repository system.

Merely by way of example, network(s)  1210  can be a local area network (LAN), such as one based on Ethernet, Token-Ring and/or the like. Network(s)  1210  can be a wide-area network and the Internet. It can include a virtual network, including without limitation a virtual private network (VPN), an intranet, an extranet, a public switched telephone network (PSTN), an infra-red network, a wireless network (e.g., a network operating under any of the Institute of Electrical and Electronics (IEEE) 802.11 suite of protocols, Bluetooth®, and/or any other wireless protocol); and/or any combination of these and/or other networks. 
     Server  1212  may be composed of one or more general purpose computers, specialized server computers (including, by way of example, PC (personal computer) servers, UNIX® servers, mid-range servers, mainframe computers, rack-mounted servers, etc.), server farms, server clusters, or any other appropriate arrangement and/or combination. Server  1212  can include one or more virtual machines running virtual operating systems, or other computing architectures involving virtualization. One or more flexible pools of logical storage devices can be virtualized to maintain virtual storage devices for the server. Virtual networks can be controlled by server  1212  using software defined networking. In various embodiments, server  1212  may be adapted to run one or more services or software applications described in the foregoing disclosure. For example, server  1212  may correspond to a server for performing processing described above according to an embodiment of the present disclosure. 
     Server  1212  may run an operating system including any of those discussed above, as well as any commercially available server operating system. Server  1212  may also run any of a variety of additional server applications and/or mid-tier applications, including HTTP servers, FTP servers, CGI (common gateway interface) servers, JAVA® servers, database servers, and the like. Exemplary database servers include without limitation those commercially available from Oracle, Microsoft, Sybase, IBM (International Business Machines), and the like. 
     In some implementations, server  1212  may include one or more applications to analyze and consolidate data feeds and/or event updates received from users of client computing devices  1202 ,  1204 ,  1206 , and  1208 . As an example, data feeds and/or event updates may include, but are not limited to, Twitter® feeds, Facebook® updates or real-time updates received from one or more third party information sources and continuous data streams, which may include real-time events related to sensor data applications, financial tickers, network performance measuring tools (e.g., network monitoring and traffic management applications), clickstream analysis tools, automobile traffic monitoring, and the like. Server  1212  may also include one or more applications to display the data feeds and/or real-time events via one or more display devices of client computing devices  1202 ,  1204 ,  1206 , and  1208 . 
     Distributed system  1200  may also include one or more databases  1214  and  1216 . Databases  1214  and  1216  may reside in a variety of locations. By way of example, one or more of databases  1214  and  1216  may reside on a non-transitory storage medium local to (and/or resident in) server  1212 . Alternatively, databases  1214  and  1216  may be remote from server  1212  and in communication with server  1212  via a network-based or dedicated connection. In one set of embodiments, databases  1214  and  1216  may reside in a storage-area network (SAN). Similarly, any necessary files for performing the functions attributed to server  1212  may be stored locally on server  1212  and/or remotely, as appropriate. In one set of embodiments, databases  1214  and  1216  may include relational databases, such as databases provided by Oracle, that are adapted to store, update, and retrieve data in response to SQL-formatted commands.

       FIG. 13  is a simplified block diagram of one or more components of a system environment  1300  by which services provided by one or more components of an embodiment system may be offered as cloud services, in accordance with an embodiment of the present disclosure. The system environment  1300  can include or implement the computing environment  100  of  FIG. 1 , the computing environment  200  of  FIG. 2 , or a combination thereof. The system environment  1300  can implement the process  600  of  FIG. 6 . In the illustrated embodiment, system environment  1300  includes one or more client computing devices  1204 ,  1206 , and  1208  that may be used by users to interact with a cloud infrastructure system  1202  that provides cloud services. The client computing devices may be configured to operate a client application such as a web browser, a proprietary client application (e.g., Oracle Forms), or some other application, which may be used by a user of the client computing device to interact with cloud infrastructure system  1202  to use services provided by cloud infrastructure system  1202 . 
     It should be appreciated that cloud infrastructure system  1202  depicted in the figure may have other components than those depicted. Further, the embodiment shown in the figure is only one example of a cloud infrastructure system that may incorporate an embodiment of the invention. For example, the cloud infrastructure system  1202  can include or implement the repository system  110  of  FIGS. 1 and 2 . In some other embodiments, cloud infrastructure system  1202  may have more or fewer components than shown in the figure, may combine two or more components, or may have a different configuration or arrangement of components. 
     Client computing devices  1204 ,  1206 , and  1208  may be devices similar to those described above for  1202 ,  1204 ,  1206 , and  1208 . 
     Although exemplary system environment  1200  is shown with three client computing devices, any number of client computing devices may be supported. Other devices such as devices with sensors, etc. may interact with cloud infrastructure system  1202 . 
     Network(s)  1210  may facilitate communications and exchange of data between clients  1204 ,  1206 , and  1208  and cloud infrastructure system  1202 . Each network may be any type of network familiar to those skilled in the art that can support data communications using any of a variety of commercially-available protocols, including those described above for network(s)  1210 . 
     Cloud infrastructure system  1202  may comprise one or more computers and/or servers that may include those described above for server  1212 . 
     In certain embodiments, services provided by the cloud infrastructure system may include a host of services that are made available to users of the cloud infrastructure system on demand, such as online data storage and backup solutions, Web-based e-mail services, hosted office suites and document collaboration services, database processing, managed technical support services, and the like. Services provided by the cloud infrastructure system can dynamically scale to meet the needs of its users. A specific instantiation of a service provided by cloud infrastructure system is referred to herein as a “service instance.” In general, any service made available to a user via a communication network, such as the Internet, from a cloud service provider&#39;s system is referred to as a “cloud service.” Typically, in a public cloud environment, servers and systems that make up the cloud service provider&#39;s system are different from the customer&#39;s own on-premises servers and systems. For example, a cloud service provider&#39;s system may host an application, and a user may, via a communication network such as the Internet, on demand, order and use the application. 
     In some examples, a service in a computer network cloud infrastructure may include protected computer network access to storage, a hosted database, a hosted web server, a software application, or other service provided by a cloud vendor to a user, or as otherwise known in the art. For example, a service can include password-protected access to remote storage on the cloud through the Internet. As another example, a service can include a web service-based hosted relational database and a script-language middleware engine for private use by a networked developer. As another example, a service can include access to an email software application hosted on a cloud vendor&#39;s web site. 
     In certain embodiments, cloud infrastructure system  1202  may include a suite of applications, middleware, and database service offerings that are delivered to a customer in a self-service, subscription-based, elastically scalable, reliable, highly available, and secure manner. An example of such a cloud infrastructure system is the Oracle Public Cloud provided by the present assignee. 
     Large volumes of data, sometimes referred to as big data, can be hosted and/or manipulated by the infrastructure system on many levels and at different scales. Such data can include data sets that are so large and complex that it can be difficult to process using typical database management tools or traditional data processing applications. For example, terabytes of data may be difficult to store, retrieve, and process using personal computers or their rack-based counterparts. Such sizes of data can be difficult to work with using most current relational database management systems and desktop statistics and visualization packages. They can require massively parallel processing software running thousands of server computers, beyond the structure of commonly used software tools, to capture, curate, manage, and process the data within a tolerable elapsed time. 
     Extremely large data sets can be stored and manipulated by analysts and researchers to visualize large amounts of data, detect trends, and/or otherwise interact with the data. Tens, hundreds, or thousands of processors linked in parallel can act upon such data in order to present it or simulate external forces on the data or what it represents. These data sets can involve structured data, such as that organized in a database or otherwise according to a structured model, and/or unstructured data (e.g., emails, images, data blobs (binary large objects), web pages, complex event processing). By leveraging an ability of an embodiment to relatively quickly focus more (or fewer) computing resources upon an objective, the cloud infrastructure system may be better available to carry out tasks on large data sets based on demand from a business, government agency, research organization, private individual, group of like-minded individuals or organizations, or other entity. 
     In various embodiments, cloud infrastructure system  1202  may be adapted to automatically provision, manage and track a customer&#39;s subscription to services offered by cloud infrastructure system  1202 . Cloud infrastructure system  1202  may provide the cloud services via different deployment models. For example, services may be provided under a public cloud model in which cloud infrastructure system  1202  is owned by an organization selling cloud services (e.g., owned by Oracle) and the services are made available to the general public or different industry enterprises. As another example, services may be provided under a private cloud model in which cloud infrastructure system  1202  is operated solely for a single organization and may provide services for one or more entities within the organization. The cloud services may also be provided under a community cloud model in which cloud infrastructure system  1202  and the services provided by cloud infrastructure system  1202  are shared by several organizations in a related community. The cloud services may also be provided under a hybrid cloud model, which is a combination of two or more different models. 
     In some embodiments, the services provided by cloud infrastructure system  1202  may include one or more services provided under Software as a Service (SaaS) category, Platform as a Service (PaaS) category, Infrastructure as a Service (IaaS) category, or other categories of services including hybrid services. A customer, via a subscription order, may order one or more services provided by cloud infrastructure system  1202 . Cloud infrastructure system  1202  then performs processing to provide the services in the customer&#39;s subscription order. 
     In some embodiments, the services provided by cloud infrastructure system  1202  may include, without limitation, application services, platform services and infrastructure services. In some examples, application services may be provided by the cloud infrastructure system via a SaaS platform. The SaaS platform may be configured to provide cloud services that fall under the SaaS category. For example, the SaaS platform may provide capabilities to build and deliver a suite of on-demand applications on an integrated development and deployment platform. The SaaS platform may manage and control the underlying software and infrastructure for providing the SaaS services. By utilizing the services provided by the SaaS platform, customers can utilize applications executing on the cloud infrastructure system. Customers can acquire the application services without the need for customers to purchase separate licenses and support. Various different SaaS services may be provided. Examples include, without limitation, services that provide solutions for sales performance management, enterprise integration, and business flexibility for large organizations. 
     In some embodiments, platform services may be provided by the cloud infrastructure system via a PaaS platform. The PaaS platform may be configured to provide cloud services that fall under the PaaS category. Examples of platform services may include without limitation services that enable organizations (such as Oracle) to consolidate existing applications on a shared, common architecture, as well as the ability to build new applications that leverage the shared services provided by the platform. The PaaS platform may manage and control the underlying software and infrastructure for providing the PaaS services. Customers can acquire the PaaS services provided by the cloud infrastructure system without the need for customers to purchase separate licenses and support. Examples of platform services include, without limitation, Oracle Java Cloud Service (JCS), Oracle Database Cloud Service (DBCS), and others. 
     By utilizing the services provided by the PaaS platform, customers can employ programming languages and tools supported by the cloud infrastructure system and also control the deployed services. In some embodiments, platform services provided by the cloud infrastructure system may include database cloud services, middleware cloud services (e.g., Oracle Fusion Middleware services), and Java cloud services. In one embodiment, database cloud services may support shared service deployment models that enable organizations to pool database resources and offer customers a Database as a Service in the form of a database cloud. Middleware cloud services may provide a platform for customers to develop and deploy various business applications, and Java cloud services may provide a platform for customers to deploy Java applications, in the cloud infrastructure system. 
     Various different infrastructure services may be provided by an IaaS platform in the cloud infrastructure system. The infrastructure services facilitate the management and control of the underlying computing resources, such as storage, networks, and other fundamental computing resources for customers utilizing services provided by the SaaS platform and the PaaS platform. 
     In certain embodiments, cloud infrastructure system  1202  may also include infrastructure resources  1230  for providing the resources used to provide various services to customers of the cloud infrastructure system. In one embodiment, infrastructure resources  1230  may include pre-integrated and optimized combinations of hardware, such as servers, storage, and networking resources to execute the services provided by the PaaS platform and the SaaS platform. 
     In some embodiments, resources in cloud infrastructure system  1202  may be shared by multiple users and dynamically re-allocated per demand. Additionally, resources may be allocated to users in different time zones. For example, cloud infrastructure system  1230  may enable a first set of users in a first time zone to utilize resources of the cloud infrastructure system for a specified number of hours and then enable the re-allocation of the same resources to another set of users located in a different time zone, thereby maximizing the utilization of resources. 
     In certain embodiments, a number of internal shared services  1232  may be provided that are shared by different components or modules of cloud infrastructure system  1202  and by the services provided by cloud infrastructure system  1202 . These internal shared services may include, without limitation, a security and identity service, an integration service, an enterprise repository service, an enterprise manager service, a virus scanning and white list service, a high availability, backup and recovery service, service for enabling cloud support, an email service, a notification service, a file transfer service, and the like. 
     In certain embodiments, cloud infrastructure system  1202  may provide comprehensive management of cloud services (e.g., SaaS, PaaS, and IaaS services) in the cloud infrastructure system. In one embodiment, cloud management functionality may include capabilities for provisioning, managing and tracking a customer&#39;s subscription received by cloud infrastructure system  1202 , and the like. 
     In one embodiment, as depicted in the figure, cloud management functionality may be provided by one or more modules, such as an order management module  1220 , an order orchestration module  1222 , an order provisioning module  1224 , an order management and monitoring module  1226 , and an identity management module  1228 . These modules may include or be provided using one or more computers and/or servers, which may be general purpose computers, specialized server computers, server farms, server clusters, or any other appropriate arrangement and/or combination. 
     In exemplary operation  1234 , a customer using a client device, such as client device  1204 ,  1206  or  1208 , may interact with cloud infrastructure system  1202  by requesting one or more services provided by cloud infrastructure system  1202  and placing an order for a subscription for one or more services offered by cloud infrastructure system  1202 . In certain embodiments, the customer may access a cloud UI, cloud UI  1212 , cloud UI  1214  and/or cloud UI  1216  and place a subscription order via these UIs. The order information received by cloud infrastructure system  1202  in response to the customer placing an order may include information identifying the customer and one or more services offered by the cloud infrastructure system  1202  that the customer intends to subscribe to. 
     After an order has been placed by the customer, the order information is received via the cloud UIs,  1212 ,  1214  and/or  1216 . 
     At operation  1236 , the order is stored in order database  1218 . Order database  1218  can be one of several databases operated by cloud infrastructure system  1218  and operated in conjunction with other system elements. 
     At operation  1238 , the order information is forwarded to an order management module  1220 . In some instances, order management module  1220  may be configured to perform billing and accounting functions related to the order, such as verifying the order, and upon verification, booking the order. 
     At operation  1240 , information regarding the order is communicated to an order orchestration module  1222 . Order orchestration module  1222  may utilize the order information to orchestrate the provisioning of services and resources for the order placed by the customer. In some instances, order orchestration module  1222  may orchestrate the provisioning of resources to support the subscribed services using the services of order provisioning module  1224 . 
     In certain embodiments, order orchestration module  1222  enables the management of business processes associated with each order and applies business logic to determine whether an order should proceed to provisioning. At operation  1242 , upon receiving an order for a new subscription, order orchestration module  1222  sends a request to order provisioning module  1224  to allocate resources and configure those resources needed to fulfill the subscription order. Order provisioning module  1224  enables the allocation of resources for the services ordered by the customer. Order provisioning module  1224  provides a level of abstraction between the cloud services provided by cloud infrastructure system  1200  and the physical implementation layer that is used to provision the resources for providing the requested services. Order orchestration module  1222  may thus be isolated from implementation details, such as whether or not services and resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request. 
     At operation  1244 , once the services and resources are provisioned, a notification of the provided service may be sent to customers on client devices  1204 ,  1206  and/or  1208  by order provisioning module  1224  of cloud infrastructure system  1202 . 
     At operation  1246 , the customer&#39;s subscription order may be managed and tracked by an order management and monitoring module  1226 . In some instances, order management and monitoring module  1226  may be configured to collect usage statistics for the services in the subscription order, such as the amount of storage used, the amount data transferred, the number of users, and the amount of system up time and system down time. 
     In certain embodiments, cloud infrastructure system  1200  may include an identity management module  1228 . Identity management module  1228  may be configured to provide identity services, such as access management and authorization services in cloud infrastructure system  1200 . In some embodiments, identity management module  1228  may control information about customers who wish to utilize the services provided by cloud infrastructure system  1202 . Such information can include information that authenticates the identities of such customers and information that describes which actions those customers are authorized to perform relative to various system resources (e.g., files, directories, applications, communication ports, memory segments, etc.) Identity management module  1228  may also include the management of descriptive information about each customer and about how and by whom that descriptive information can be accessed and modified. 
       FIG. 14  illustrates an exemplary computer system  1400 , in which various embodiments of the present invention may be implemented. The system  1400  may be used to implement any of the computer systems described above. For example, all or some of the elements of the computing environment  100  of  FIG. 1 , the computing environment  200  of  FIG. 2 , or a combination thereof, can be included or implemented in the system  1400 . The system  1400  can implement the process  600  of  FIG. 6 . As shown in the figure, computer system  1400  includes a processing unit  1404  that communicates with a number of peripheral subsystems via a bus subsystem  1402 .

In general, use of the term “output device” is intended to include all possible types of devices and mechanisms for outputting information from computer system  1400  to a user or other computer. For example, UI output devices may include, without limitation, a variety of display devices that visually convey text, graphics and audio/video information such as monitors, printers, speakers, headphones, automotive navigation systems, plotters, voice output devices, and modems. 
     Computer system  1400  may comprise a storage subsystem  1418  that comprises software elements, shown as being currently located within a system memory  1410 . System memory  1410  may store program instructions that are loadable and executable on processing unit  1404 , as well as data generated during the execution of these programs. 
     Depending on the configuration and type of computer system  1400 , system memory  1410  may be volatile (such as random access memory (RAM)) and/or non-volatile (such as read-only memory (ROM), flash memory, etc.) The RAM typically contains data and/or program modules that are immediately accessible to and/or presently being operated and executed by processing unit  1404 . In some implementations, system memory  1410  may include multiple different types of memory, such as static random access memory (SRAM) or dynamic random access memory (DRAM).

The disk drives and their associated computer-readable media may provide non-volatile storage of computer-readable instructions, data structures, program modules, and other data for computer system  1400 . 
     Communications subsystem  1424  provides an interface to other computer systems and networks. Communications subsystem  1424  serves as an interface for receiving data from and transmitting data to other systems from computer system  1400 . For example, communications subsystem  1424  may enable computer system  1400  to connect to one or more devices via the Internet. In some embodiments communications subsystem  1424  can include radio frequency (RF) transceiver components for accessing wireless voice and/or data networks (e.g., using cellular telephone technology, advanced data network technology, such as 3G, 4G or EDGE (enhanced data rates for global evolution), WiFi (IEEE 802.11 family standards, or other mobile communication technologies, or any combination thereof), global positioning system (GPS) receiver components, and/or other components. In some embodiments communications subsystem  1424  can provide wired network connectivity (e.g., Ethernet) in addition to or instead of a wireless interface. 
     In some embodiments, communications subsystem  1424  may also receive input communication in the form of structured and/or unstructured data feeds  1426 , event streams  1428 , event updates  1430 , and the like on behalf of one or more users who may use computer system  1400 . 
     By way of example, communications subsystem  1424  may be configured to receive data feeds  1426  in real-time from users of social media networks and/or other communication services such as Twitter® feeds, Facebook® updates, web feeds such as Rich Site Summary (RSS) feeds, and/or real-time updates from one or more third party information sources. 
     Additionally, communications subsystem  1424  may also be configured to receive data in the form of continuous data streams, which may include event streams  1428  of real-time events and/or event updates  1430 , that may be continuous or unbounded in nature with no explicit end. Examples of applications that generate continuous data may include, for example, sensor data applications, financial tickers, network performance measuring tools (e.g. network monitoring and traffic management applications), clickstream analysis tools, automobile traffic monitoring, and the like. 
     Communications subsystem  1424  may also be configured to output the structured and/or unstructured data feeds  1426 , event streams  1428 , event updates  1430 , and the like to one or more databases that may be in communication with one or more streaming data source computers coupled to computer system  1400 .
