## Title
Generation of a data model applied to queries

## Abstract

Embodiments include generating data models that may give semantic meaning for unstructured or structured data that may include data generated and/or received by search engines, including a time series engine. A method includes generating a data model for data stored in a repository. Generating the data model includes generating an initial query string, executing the initial query string on the data, generating an initial result set based on the initial query string being executed on the data, determining one or more candidate fields from one or results of the initial result set, generating a candidate data model based on the one or more candidate fields, iteratively modifying the candidate data model until the candidate data model models the data, and using the candidate data model as the data model.

## Background
RELATED APPLICATIONS
The present application is a Continuation of U.S. application Ser. No. 14/067,203 filed Oct. 30, 2013, entitled “GENERATION OF A DATA MODEL FOR SEARCHING MACHINE DATA”, now U.S. Pat. No. 8,983,994, issued 17 Mar. 2015, which is a Continuation of U.S. application Ser. No. 13/607,117 filed Sep. 7, 2012, entitled “DATA MODEL FOR MACHINE DATA FOR SEMANTIC SEARCH,” now U.S. Pat. No. 8,788,525, issued 22 Jul. 2014, both of which applications are incorporated herein by reference in their entirety.


BACKGROUND OF THE INVENTION
This invention relates generally to information organization, data modeling, search, and retrieval and more particularly, the generating and utilizing data models in search, and retrieval of search engine data.
The rapid increase in the production and collection of machine generated data has created relatively large data sets that are difficult to search. The machine data can include sequences of time stamped records that may occur in one or more usually continuous streams. Further, machine data often represents some type of activity made up of discrete events.
Often, searching large data sets requires different ways to express search criteria. Search tools today typical allow users to search by the most frequently occurring terms or keywords within the data and generally have little notion of event based searching. Given the large volume and typically repetitive characteristics of machine data, users often need to start by narrowing the set of potential search results using event-based search mechanisms and then, through examination of the results, choose one or more keywords to add to their search parameters. Timeframes and event-based metadata like frequency, distribution, and likelihood of occurrence are especially important when searching data, but can be difficult to achieve with current search tools.
Also, users often generate ad-hoc queries to produce results from data repositories. In some cases, generating queries sufficient for retrieving the desired results may require an undesirably high-level of knowledge about the data domain and/or the operation/structure of the data repository. Thus, systems related to the searching of relatively large sets of data are the subject of considerable innovation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Various embodiments now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments by which the invention may be practiced. The embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the embodiments to those skilled in the art. Among other things, the various embodiments may be methods, systems, media or devices. Accordingly, the various embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.
Throughout the specification and claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment, though it may. Furthermore, the phrase “in another embodiment” as used herein does not necessarily refer to a different embodiment, although it may. Thus, as described below, various embodiments may be readily combined, without departing from the scope or spirit of the invention.
In addition, as used herein, the term “or” is an inclusive “or” operator, and is equivalent to the term “and/or,” unless the context clearly dictates otherwise. The term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”
For example embodiments, the following terms are also used herein according to the corresponding meaning, unless the context clearly dictates otherwise.
The term “machine data” as used herein may include server logs and other types of machine data (i.e., data generated by machines). In at least one of the various embodiments, machine data streams may be time stamped to create time stamped events. For example, information processing environments, such as, firewalls, routers, web servers, application servers and databases may generate streams of time series data in the form of events. In some cases, events may be generated hundreds or thousands of times per second.
The term “time series data” as used herein is data where each data record has a timestamp associated with it. A “Time Series Search Engine” is a search engine which, in at least one of the various embodiments, can perform queries on the stored data limited by a time range (such as between one time and another, or data earlier than a given time, or the like) and/or generates results ordered by time and/or timestamps (such as from earliest-to-latest or vice versa).
The term “data repository” as used herein refers to data sources that may contain unstructured or structured data, such as databases, file systems, search engine indexes, or the like. In at least one of the various embodiments, data repository may be a live stream of data. In other cases, data repository may be static data, or combination of live data or static data. In at least one of the various embodiments, data repositories may provide interfaces and/or application programming interfaces (API) for receiving requests, queries, or searches regarding the data stored in the data repository.
The term “query string” as used herein refers to commands and/or sequences of commands that are used for querying, searching and/or retrieving data from a data repository. Queries generally produce a result or results based on the form and structure of the particular query string. Query results may be sorted and grouped based on the structure and form of the query string. In at least one of the various embodiments, query strings may include operators and functions for calculating values based on the stored records, including functions that produce result sets that may include statistics and metrics about the data stored in data repository. Structured Query Language (SQL) is a well-known query language often used to form queries for relational databases. However, the various embodiments are not limited to using SQL-like formatting for query strings. Accordingly, other well-known query languages and/or custom query languages may be employed consistent with what is claimed herein.
The following briefly describes the embodiments of the invention in order to provide a basic understanding of some aspects of the invention. This brief description is not intended as an extensive overview. It is not intended to identify key or critical elements, or to delineate or otherwise narrow the scope. Its purpose is merely to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
Briefly stated, various embodiments are directed towards generating data models that may at least define semantic meaning for modeling unstructured data and/or structured data that may be stored in a data repository. In at least one of the various embodiments, unstructured data may include data generated and/or received by search engines, including a time series search engine. Also, in at least one of the various embodiments, unstructured data may be received and/or stored absent pre-defined data schemas or formats. In at least one of the various embodiments, data models also may be generated to provide at least semantic meaning to structured data that may be stored in Structured Query Language (SQL) databases, Extensible Markup Language (XML) files, or the like.
In at least one of the various embodiments, the data model may be determined such that it at least provides semantic meaning to unstructured data. In at least one of the various embodiments, data models may be generated to provide at least semantic meaning to unstructured data without creating a static database schema. Further, in at least one of the various embodiments, one or more data models may be generated such that the organization of the unstructured may remain unmodified. Thus, data models, in at least one of the various embodiments, may provide semantic meaning to unstructured data without modifying the unstructured data (e.g., no side-effects).
In at least one of the various embodiments, a data model may be composed of one or more data model objects. In at least one of the various embodiments, data model objects may have a hierarchy analogous to an object-oriented programming class hierarchy. Further, in at least one of the various embodiments, data model objects may include fields, filters, constraints, or the like, that correspond to the data the data model object represents.
In at least one of the various embodiments, users may employ a data modeling application to produce a report using search objects that may be part of, or associated with the data model. The data modeling application may employ the search objects and the data model to generate a query string for searching a data repository to produce a result set. In at least one of the various embodiments, the data modeling application may map the result set data to data model objects that may be used to generate reports.
In at least one of the various embodiments, a search object may be an individual data model object selected by a user to generate search results. In this case, a search object may be a data model object selected from among the data model objects that comprise a data model. Also, in at least one of the various embodiments, search objects may be specialized objects that may include one or more data model objects, portions of one or more data model objects, or the like. In some embodiments, search objects may include fields, filters, constraints, that may be separate from those comprising data model objects.

a model schema that references fields that can be extracted, by an extraction rule or regular expression, from the unstructured data in the time stamped events without modifying the unstructured data; and
one or more submodels;

each of the submodels comprising:
a child object that provides for narrower search criteria than the root object query such that, when the child object query is executed against the time stamped events, the child object query returns a subset of the set of time stamped events that is smaller than the set;
a submodel schema that inherits one or more fields referenced in the model schema; and
the submodel schema further references additional fields that can be extracted, by an extraction rule or regular expression, from the unstructured data in the time stamped events without modifying the unstructured data;

receiving electronically a data request comprising reference to a submodel selected from the data model structure and a query to be performed against the subset referenced by the selected submodel; and
identifying responsive events, including extracting values from at least some of the events in the subset at query time using the extraction rule or regular expression in the submodel schema without modifying the unstructured event and matching the extracted values to the query;
returning at least some values from or derived from the fields in the responsive events referenced by the submodel schema.

2. The method of claim 1, wherein the values derived from the fields in the responsive events are results of aggregate calculations from the values in the fields of responsive events.

3. The method of claim 1, further including causing display of the values from or derived from the fields in the responsive events as values in rows in a pivot report template.

4. A method, comprising:
receiving a selection of an object included in a data model that has both a root object and at least one child object;
the root object includes:
a root object query that, when executed, returns a set of time stamped events from a data store on a computing device, each event including a portion of raw machine data; and
a root object schema identifying a set of one or more fields, each field defined by an extraction rule or regular expression that can be used to extract a value for the field from each event in a subset of the set of time stamped events, each extraction operating on the raw machine data in an event without modifying the event's raw machine data;

the at least one child object includes:
a child object query that provides for narrower search criteria than the root object query such that, when the child object query is executed against the time stamped events in the data store, the child object query returns a second set of time stamped events that is a subset of the set of time stamped events generated by executing the root object query against the time stamped events in the data store; and
a child object schema identifying a second set of one or more fields, each field defined by an extraction rule or regular expression that can be used to extract a value for the field from each event in a subset of the second set of time stamped events, each extraction operating on the raw machine data in an event without modifying the event's raw machine data;
receiving from a user a search query that uses only fields that are included in the object schema of the selected object; and
executing the search query received from the user only against the set of time stamped events generated by executing the object query of the selected object against the set of time stamped events in the data store.

5. The method of claim 4,
wherein the second set of one or more fields comprises a subset of the set of one or more fields identified by the root object schema.

6. The method of claim 4,
wherein the second set of one or more fields comprises both (i) a subset of the set of one or more fields identified by the root object schema, and (ii) additional fields not identified by the root object schema.

7. The method of claim 4,
wherein the second set of one or more fields has no fields in common with the set of one or more fields identified by the root object schema.

8. The method of claim 4, wherein the selection of the data model is indicated by receiving a selection of an object included in the data model.

9. The method of claim 4, wherein the selection of the data model is indicated by receiving a selection of a root object or child object included in the data model.

10. The method of claim 4, further comprising causing display of references to a plurality of data models in a graphical user interface enabling selection of a data model, and wherein the selection of the data model is received through the graphical user interface.

11. The method of claim 4, further comprising causing display of references to a plurality of data models in a graphical user interface that enables hierarchical display of child objects included in a data model for which a reference has been displayed.

12. The method of claim 4, further comprising:
populating a pivot graphical user interface with controls for manipulating data that correspond to the set of one or more fields in the root object schema for the selected data model, and wherein the pivot graphical user interface enables a user to further filter the set of time stamped events that are returned when the root object query is executed against the set of time stamped events in the data store.

13. The method of claim 4, further comprising:
populating a pivot graphical user interface with controls for manipulating data that correspond to the set of one or more fields in the root object schema for the selected data model, and wherein the pivot graphical user interface enables a user to perform aggregate calculations on a field in the set of time stamped events that are returned when the root object query is executed against the set of time stamped events in the data store.

14. The method of claim 4, further comprising:
populating a pivot graphical user interface with controls for manipulating data that correspond to the set of one or more fields in the root object schema for the selected data model, and wherein the pivot graphical user interface enables a user to generate a data visualization whose features depend on fields or criteria for fields in the set of time stamped events that are returned when the root object query is executed against the set of time stamped events in the data store.

15. The method of claim 4, further comprising:
populating a pivot graphical user interface with controls for manipulating data that correspond to a set of one or more fields in an object schema included in an object in the selected data model, and wherein the pivot graphical user interface enables a user to thither filter the set of time stamped events that are returned when a child object query included in the object is executed against the set of time stamped events in the data store.

16. The method of claim 4, further comprising:
populating a pivot graphical user interface with controls for manipulating data that correspond to a set of one or more fields in an Object schema included in an object in the selected data model, and wherein the pivot graphical user interface enables a user to perform aggregate calculations on a field in a set of time stamped events that are returned when an object query in the object is executed against the set of time stamped events in the data store.

17. The method of claim 4, further comprising:
populating a pivot graphical user interface with controls for manipulating data that correspond to a set of one or more fields in an object schema included in an object in the selected data model, and wherein the pivot graphical user interface enables a user to generate a data visualization whose features depend on fields or criteria for fields in the set of time stamped events that are returned when an object query in the object is executed against the set of time stamped events in the data store.
