## Title
Mapping of client application variable to database storage location free of allocation to any particular variable

## Abstract

An apparatus in one example comprises a management component that handles information storage to one or more storage locations of a database. The one or more storage locations comprise one or more available locations that are free of allocation to any particular variable. The management component maps one or more variables of one or more client applications to respective one or more selected locations of the one or more available locations.

## Background
TECHNICAL FIELD
The invention relates generally to information management and more particularly to handling of variables for client applications.
BACKGROUND
A database, in one system, is created with a fixed number of storage locations. The storage locations are pre-defined to store specific variables of a particular client application. The specific variables employed by the particular client application may be different from variables that are employed by another client application.
As one shortcoming of such a system, separate databases must be designed whenever the specific variables of each client application differ. The pre-defined storage locations in the database limit the number of different client applications that will be able to use the database. If a first client application needs storage for three specific variables in each record of the database, then all the records of the database must be designed with three data fields set to store only the three specific variables. If a second client application needs storage for variables that in any way differ from the specific variables of the first client application, then the version of the database designed for the first client application cannot be used by the second client application. So, the pre-defined storage locations of the database undesirably create a likelihood that the database will be incompatible with different client applications.
As another shortcoming of the system, the fixed number of storage locations pre-defined for each record undesirably restrict a client application from employing any greater number of variables with each record in the database. If the client application undergoes an update and requires an additional storage location in the database to accommodate a new variable, then a corresponding update of the database is required.
As a further shortcoming of the system, the fixed number of storage locations pre-defined for each record in the database represents an inefficient use of the database. Not every client application uses all the storage locations allocated for each record. The unused yet specifically allocated storage locations of one record cannot be used for any other records. In addition, the predefinition of storage locations results in an undesirably low limit on the total number of records that can exist in the database.
Thus, a need exists for enhanced database storage of variables from client applications. A need also exists for enhanced accessibility to such variables. A further need exists for enhanced accommodation of changing needs of client applications with respect to variables.

DETAILED DESCRIPTION
Turning to FIG. 1, an apparatus 100 in one example comprises a management component that handles information storage to one or more storage locations of a database. The one or more storage locations comprise one or more available locations that are free of allocation to any particular variable. The management component maps one or more variables of one or more client applications to respective one or more selected locations of the one or more available locations. The apparatus 100 includes a plurality of components such as computer software and/or hardware components. A number of such components can be combined or divided in the apparatus 100.
The apparatus 100 in one example employs at least one computer-readable signal-bearing medium. One example of a computer-readable signal-bearing medium for the apparatus 100 comprises an instance of a recordable data storage medium 101 such as one or more of a magnetic, electrical, optical, biological, and atomic data storage medium. In another example, a computer-readable signal-bearing medium for the apparatus 100 comprises a modulated carrier signal transmitted over a network comprising or coupled with the apparatus 100, for instance, one or more of a telephone network, a local area network (“LAN”), the internet, and a wireless network. An exemplary component of the apparatus 100 employs and/or comprises a set and/or series of computer instructions written in or implemented with any of a number of programming languages, as will be appreciated by those skilled in the art.
In one example, the apparatus 100 serves as a database management system. In a further example, the apparatus 100 serves as a telecommunications subscriber database management system. The apparatus 100 comprises one or more databases 102, one or more management components 104, one or more provisioning components 106, and one or more client applications 108 and/or 110. The database 102 in one example is located in a storage device. The recordable data storage medium 101 and the database 102 in one example are located in a same storage medium. In another example, the recordable data storage medium 101 and the database 102 are located in different storage media. In a further example, the database 102 comprises a plurality of databases. One or more of users 124, 126, 128, and 130 interact with the client applications 108 and/or 110. The users 124, 126, 128, and 130 comprise one or more of human operators, hardware entities, and software entities.
The management component 104 serves as an interface between the database 102 and the client applications 108 and 110. The management component 104 comprises a primary channel for data flow through the apparatus 100. The management component 104 creates a one-to-one mapping of a variable of the client application 108 to a storage location of the database 102 that is free of allocation to any particular variable and comprises a capacity corresponding to a data type of the variable.
Now referring to FIGS. 1–3, the database 102 comprises storage portions 222 and/or 302. The storage portions 222 and 302 comprise one or more storage locations. Exemplary storage locations of the database 102 comprise storage locations 234, 236, 238, 240, 242, 304, and 306. The storage portion 222 comprises one or more storage locations for which the database 102 is without any expectation of the particular variables of the client applications 108 and/or 110 to be stored therein. The storage locations, of the storage portion 222, are initially free of allocation to any particular variable. The storage portion 302 comprises one or more storage locations pre-allocated in the database 102 to store specific variables of the client applications 108 and/or 110. Further below is presented an illustrative description of first, second, and third exemplary implementations of the database 102 with reference to FIG. 1 in conjunction with FIGS. 2, 3, and 4, respectively.
Referring to FIGS. 1–2, the database 102 comprises one or more records. The records comprise a changeable number of storage locations. The number of the storage locations in a record changes with the needs of the client application 108. Exemplary records of the database 102 comprise records 202, 204, 206, 208, 210, 212, and 214, as described herein. One or more of the records of the database 102 are associated with one or more of the client applications 108 and/or 110. For example, the record 202 stores the variables used by the client application 108.
The provisioning component 106 performs a selection of storage locations from the storage portion 222 based on the storage needs of the client applications 108 and/or 110. When the client application 108 needs one or more of the storage locations of the storage portion 222 for storage of a variable, the provisioning component 106 performs the selection to coordinate the data type of the variable with the capacity of a storage location of the storage portion 222. The provisioning component 106 passes the result of the selection to the management component 104. Additional illustrative discussion of exemplary operation of the management component 104 and the provisioning component 106 is presented herein, for explanatory purposes.
Referring to FIG. 2, the storage locations of the storage portion 222 are designed to store variables of any name. Initially, the storage locations of the storage portion 222 are available to store any variable. The available storage locations of the storage portion 222 are free of allocation to any particular variable. Based on the needs of the client applications 108 and/or 110, the management component 104 soft allocates available storage locations of the storage portion 222 to store variables of the client applications 108 and/or 110, as described herein.
In one example, the soft allocation is temporary. At one point in time, the management component 104 allocates a certain storage location of the storage portion 222 to store a first variable. At a subsequent point in time, the management component 104 frees the certain storage location from allocation to store the first variable. For example, the client application 108 no longer has a need for the first variable. Thereafter, the management component 104 can allocate the certain storage location to store a second variable.
The management component 104 receives requests from the client application 108 to store variables in the database 102. The management component 104 accommodates the client application 108 upon presentation of a variable for which none of the storage locations of the storage portion 302 have been pre-allocated to store the variable. For example, the management component 104 employs one of the storage locations of the storage portion 222 to store the variable.
Referring to FIGS. 1–2, the management component 104 serves as an interface for the client application 108 to store the variable in the database 102. From the perspective of the database 102, the management component 104 serves to translate the name of a variable employed by the client application 108 to a reference name employed by the database 102 for a storage location of the storage portion 222 selected to store the variable, as described herein. From the perspective of the client application 108, the management component 104 serves to translate the reference name of the selected storage location of the storage portion 222, employed by the database 102, to the name of the variable employed by the client application 108. Furthermore, neither the client application 108 nor the database 102 needs to know the details of the name translation. The client application 108 and the database 102 trust the management component 104 to map the variable to the storage location.
The provisioning component 106 serves to select the storage location 234 to store the variable based on one or more characteristics of the variable, for example, one or more of type, size, and length of the variable. For example, the provisioning component 106 performs the selection by matching a data type of the variable to a corresponding capacity of the storage location 234. In one example, the data type of the variable comprises an integer, and storage location 234 comprises a corresponding capacity to store an integer. The provisioning component 106 reviews the available storage locations of the storage portion 222 to select the storage location 234. Next, the provisioning component 106 communicates the selection of the storage location 234 to the management component 104, to accommodate the variable. The management component 104 employs the selection by the provisioning component 106 to map the variable to the storage location 234. The storage location 234 in one example is associated with the record 202 when the storage location is allocated to the variable. In one example, an account of the client application 108 is associated with the record 202. In a further example, the management component 104 associates the storage location 234 with the record 202 upon introduction of the variable to the management component 104 as associated with the account already associated with the record 202.
Referring to FIG. 3, the storage portion 302 comprises one or more storage locations pre-allocated to store specific variables. The database designer decides which variables to accommodate in the storage portion 302 based on the variables with a name common to the client applications 108 and 110. The storage locations of the storage portion 302 are reserved for one or more expected variables of the client applications 108 and/or 110. For example, a designer of the database 102 designates the storage locations of the storage portion 302 to store predetermined variables of the client applications 108 and 110. The database designer defines the storage locations of the storage portion 302 to have specific names. The specific names of the storage locations of the storage portion 302 correspond to predetermined names of the expected variables. For example, the storage locations of the storage portion 302 are hard allocated to store the expected variables.
When the client application 108 presents an expected name to the management component 104, the management component 104 maps the predetermined variable to the pre-allocated storage location of the storage portion 302. In one example, the management component 108 performs one or more additional checks as part of the mapping. When the client application 108 introduces to the management component 104 a variable with a name other than the names expected for the storage locations of the storage portion 302, the management component 108 maps the variables to the storage locations of the storage portion 222, as described herein.
The record 202 in one example comprises one or more storage locations pre-allocated to store specific variables. The designer of the database 102 decides which variables to accommodate in an individual record based on the individual requirements of the client applications 108 and/or 110 for variables. A first record of the database 102 may have one or more storage locations pre-allocated to store variables with names different from names of variables stored in storage locations of a second record of the database 102. Should the client application 108 employ the record 202, the management component 104 allows the client application 108 to use any of the storage locations within the record 202.
In a first exemplary implementation of the database 102, referring to FIGS. 1–2, all the records of the database 102 are initially free of association with any particular variables of the client applications 108 and 110. The database 102 comprises the storage locations of the storage portion 222 ready for allocation to the records as directed by the management component 104 in accommodation of the client applications 108 and 110.
In a second exemplary implementation of the database 102, referring to FIGS. 1 and 3, the records of the database 102 comprises the storage locations of the storage portion 222 and the storage locations of the storage portion 302. The storage portion 222 is initially free of association with any record of the database 102. In addition, the storage portion 222 is without any expectation of the identities of the variables to be store in the storage portion 222. For example, the storage location 234 is ready to store any variable of the client application 108 and/or 110 of a data type corresponding to a capacity of the storage location 234, as directed by the management component 104. The storage portion 302 comprises storage locations that are pre-associated with particular records and pre-allocated to store specific variables of client applications 108 and/or 110.
In a third exemplary implementation of the database 102, referring to FIGS. 1 and 4, the records of the database 102 are pre-configured to comprise set storage locations of the storage portion 222 and the storage portion 302. A record of the database 102 comprises a preset number of storage locations pre-allocated to predetermined variables and a preset number of storage locations available for dynamic assignment to new variables.
The designer of the database 102 decides upon the capacity and number of storage locations of the storage portions 222 and/or 302 through analysis of expected needs of features to be supported by the client applications 108 and/or 110. The storage location 234 comprises a set size and/or capacity. The name of the storage location 234 is a reference index specific to the database 102. The client applications 108 in one example is unaware of the name of the storage location 234 in the database 102. Instead, the client application 108 trusts the management component 104 to handle mapping of a variable employed by the client application 108 to the storage location 234.
The storage locations of the storage portion 222 are designed to store one or more data types. In one example, the storage location 234 is pre-formatted to store an integer type. In another example, the storage location 234 is pre-formatted to store a string type. In yet another example, the storage location 234 is pre-formatted to store a double type.
The management component 104 employs a table 105. The management component 104 references the table 105 when processing and communicating requests from the client application 108 and/or 110 and replies from the database 102. The management component 104 in one example hides the mapping information of the table 105 from the database 102 and the client applications 108 and/or 110. The management component 104 stores a specific variable of the client application 108 in any available one of the storage locations of the storage portion 222 that comprise a capacity corresponding to the data type of the variable.
The client application 108 in one example is not concerned and/or aware that the database 102 does not have a pre-allocated storage location of the storage portion 222 for each of the variables of the client application 108. The client application 108 trusts the management component 104 to handle the storage of the variables of the client application 108. When a variable of the client application 108 is stored in a storage location of portion 222, the management component 104 makes the database 102 believe that the name of the variable employed by the client application 108 is the same as the reference name of the storage location of the storage portion 222 employed by the database 102.
Now referring to FIGS. 1 and 5, the table 105 keeps a list of all variable mappings made by the management component 104. For example, the table 105 comprises a database index table 105. The table comprises one or more entries, for example, entries 502, 504, 506, and 508. The number of entries of the table 105 at a particular time in one example equals the number of variables of the client applications 108 and/or 110 for which the management component 108 at the particular time maintains mapping to storage locations of the database 102.
The entry 502 indicates the location of a variable of the client application 108 in the database 102. The entry 502 comprises one or more of a client application index 520, a client application associated variable name 522, a database associated field name 524, and an account number index 526. The management component 104 references the table 105 when the client application 108 requests access to a variable stored in the database 102. In one example, the access to the variable involves an operation to be performed on the variable. Exemplary operations comprise one or more of modify, delete, and retrieve.
Referring to FIGS. 1, 2, and 5, now is presented an illustrative description of exemplary allocation of the storage location 234 to a variable of the client application 108. The client application 108 desires to store a variable in one of the available storage locations of the storage portion 222. The client application 108 sends a request to the management component 104. One example of the request is the client application 108 introducing a variable named SUBSCRIBER NUMBER to be used by the client application 108 in conjunction with the database 102. In addition, the request from the client application 108 to the management component 104 indicates that the variable SUBSCRIBER NUMBER is to be associated with ACCOUNT #X. The client application 108 needs a storage location of the integer type to store SUBSCRIBER NUMBER. The client application 108 sends the request to the management component 104.
The management component 104 makes a determination whether a storage location of the database 102 has been allocated for the variable SUBSCRIBER NUMBER. For example, the management component 104 employs the table 105 to determine if a storage location of the database 102 has been allocated to the variable SUBSCRIBER NUMBER. If there is not an entry in the table 105 for the variable SUBSCRIBER NUMBER, then the management component 104 allocates therefor a storage location from storage portion 222.
To determine the storage location from storage portion 222 for the variable SUBSCRIBER NUMBER, the management component 104 communicates with the provisioning component 106. The provisioning component 106 selects the storage location of the storage portion 222 by correlating the capacity of the storage location with the data type of the variable SUBSCRIBER NUMBER.
For ACCOUNT #X, the provisioning component 106 selects the storage location INTEGER1 of storage portion 222 to store the variable SUBSCRIBER NUMBER of the client application 108. For example, the database 102 knows the storage location INTEGER1 as the storage location 234. The management component 104 accommodates the variable SUBSCRIBER NUMBER by mapping the request of the client application 108 to the storage location 234. The management component 104 records the mapping of the variable SUBSCRIBER NUMBER in the entry 502 of the table 105. No update of the database 102 is needed even though the client application 108 has employed the storage location 234 of the storage portion 222 to store the variable SUBSCRIBER NUMBER.
Another example illustrates the client application 108 modifying the selected storage location 234, that was originally free of allocation to any particular variable, but has subsequently been allocated to a specific variable of the client application 108. When the client application 108 desires to modify the contents of the storage location 234 that has been allocated to a specific variable of the client application 108, the client application 108 sends a request to the management component 104. In one example, the client application requests access to the record of ACCOUNT #X. For example, the client application 108 request that the value of the variable SUBSCRIBER NUMBER be changed to store the value Z.
The management component 104 translates the request from the client application 108 by referencing the entry 502 of the table 105. The request of the client application 108 is translated into a request that will be understood by the database 102. One example of the request understandable by the database 102 is a request to access the record of ACCOUNT #X and change the value of the variable INTEGER1 to the value Z. The management component 104 sends the request to the database 102 for execution.
Yet another example illustrates saving of space in the database 102 when a plurality of the client applications 108 and 110 use the database 102. The client application 108 can use the storage location 234 for a one variable at a one time, and upon release of the storage location 234 by the management component 108 after termination of the use thereof by the client application 108, the client application 110 can use the storage location 234 for another variable at another time. Such reuse of the storage location 234 allows multiple client applications with different variables to use the same version of the database 102.
For example, the client application 110 desires to store a variable in one of the available storage locations of the storage portion 222. The client application 110 sends a request to the management component 104. One example of the request is the client application 110 introducing a variable named SOCIAL SECURITY NUMBER for ACCOUNT #Y. The client application 110 needs a new storage location of the integer type to store the variable SOCIAL SECURITY NUMBER. The client application 110 sends the request to the management component 104.
The provisioning component 106 creates a selection of the storage location 234 by coordinating the data type of the variable SOCIAL SECURITY NUMBER with the corresponding capacity of the storage location 234. For example, the provisioning component 106 references ACCOUNT #Y and selects the storage location INTEGER1 to store the variable SOCIAL SECURITY NUMBER of the client application 110, where the storage location INTEGER1 is the name known to the database 102 for the storage location 234.
The management component 104 processes the request of the client application 110 based on the selection by provisioning component 106 of the storage location 234. The management component 104 records the mapping of the variable SOCIAL SECURITY NUMBER of the client application 110 into the entry 502 of the table 105. For example, the management component 104 updates the table 105 to record that for ACCOUNT #Y, the variable SOCIAL SECURITY NUMBER of the client application 110 can be found in the storage location INTEGER1. The database 102 in one example requires no update even though the client application 110 needed the storage location 234 in the database 102 to store the variable SOCIAL SECURITY NUMBER.
The steps or operations described herein are just exemplary. There may be many variations to these steps or operations without departing from the sprit of the invention. For instance, the steps may be performed in a differing order, or steps may be added, deleted, or modified.
Although exemplary implementations of the invention have been depicted and described in detail herein, it will be apparent to those skilled in the relevant art that various modifications, additions, substitutions, and the like can be make without departing from the sprit of the invention and these are therefore considered to be within the scope of the invention as defined in the following claims.
