Abstract

A method for analyzing a target system that includes obtaining a plurality of characteristics from the target system using a characteristics extractor, wherein the plurality of characteristics is associated with a characteristics model, storing each of the plurality of characteristics in a characteristics store using a tracking mechanism, and analyzing the target system by issuing a query to the characteristics store to obtain an analysis result, wherein the query uses tracking information associated with the tracking mechanism.

Claims

1. A method for analyzing a target system, comprising:

obtaining a characteristics model;

generating a characteristics extractor associated with the characteristics model;

obtaining a plurality of characteristics from the target system using the characteristics extractor, wherein the plurality of characteristics is associated with the characteristics model configured to define each of the plurality of characteristics in a particular domain, wherein the particular domain corresponds to a grouping of related characteristics, and wherein the particular domain comprises at least one hardware component and at least one software component, wherein there is a relationship between the at least one hardware and software components;

storing each of the plurality of characteristics in a characteristics store using a tracking mechanism configured to track changes to target system characteristics in the particular domain over time;

generating a characteristics store application programming interface (API) associated with the characteristics model, wherein the characteristics extractor uses the characteristics store API to store each of the plurality of characteristics in the characteristics store;

analyzing the target system in the particular domain by issuing a query to the characteristics store to obtain an analysis result, wherein the query uses tracking information associated with the tracking mechanism; and

displaying the analysis result on a display associated with a computing device.

2. The method of claim 1, wherein the tracking mechanism comprises storing a time-based attribute associated with each of the plurality of characteristics in the characteristics store.

3. The method of claim 2, wherein the time-based attribute comprises at least one selected from the group consisting of a timestamp and a target system version number.

4. The method of claim 1, wherein the characteristics store comprises a first sub-characteristics store and a second sub-characteristics store.

5. The method of claim 4, wherein the tracking mechanism comprises storing characteristics associated with a first timeframe in the first sub-characteristics store and storing characteristics associated with a second timeframe in the second sub-characteristics store.

6. The method of claim 4, wherein the tracking mechanism comprises storing characteristics associated with a first version of the target system in the first sub-characteristics store and storing characteristics associated with a second version of the target system in the second sub-characteristics store.

7. The method of claim 1, wherein the tracking information comprises one selected from the group consisting of a time-related attribute and a sub-characteristics store name.

8. The method of claim 1, wherein the at least one query is defined using a pattern query language and wherein the pattern query language includes functionality to search for at least one pattern in the target system.

9. A computer system, comprising:

a processor;

a characteristics model defining at least one artifact and a plurality of characteristics associated with the at least one artifact for a particular domain, wherein the particular domain corresponds to a grouping of related artifacts, and wherein the particular domain comprises at least one hardware component and at least one software component, wherein there is a relationship between the at least one hardware and software components;

a target system comprising at least one of the plurality of characteristics defined in the characteristics model;

at least one characteristics extractor associated with the characteristics model and configured to obtain at least one of the plurality of characteristics from the target system;

a characteristics store configured to store the at least one of the plurality of characteristics obtained from the target system using a tracking mechanism configured to track changes to target system artifacts in the particular domain over time;

a characteristics store application programming interface (API) associated with the characteristics model, wherein the characteristics extractor uses the characteristics store API to store each of the plurality of characteristics in the characteristics store; and

a query engine executed by the processor and configured to analyze the target system in the particular domain by issuing a query to the characteristics store and configured to obtain an analysis result in response to the at least one query, wherein the query uses tracking information associated with the tracking mechanism.

10. The computer system of claim 9, wherein the tracking mechanism comprises storing a time-based attribute associated with each of the plurality of characteristics in the characteristics store.

11. The computer system of claim 10, wherein the time-based attribute comprises at least one selected from the group consisting of a timestamp and a target system version number.

12. The computer system of claim 9, wherein the characteristics store comprises a first sub-characteristics store and a second sub-characteristics store.

13. The computer system of claim 12, wherein the tracking mechanism comprises storing characteristics associated with a first timeframe in the first sub-characteristics store and storing characteristics associated with a second timeframe in the second sub-characteristics store.

14. The computer system of claim 12, wherein the tracking mechanism comprises storing characteristics associated with a first version of the target system in the first sub-characteristics store and storing characteristics associated with a second version of the target system in the second sub-characteristics store.

15. The computer system of claim 9, wherein the tracking information comprises one selected from the group consisting of a time-related attribute and a sub-characteristics store name.

16. The computer system of claim 9, wherein the at least one query is defined using a pattern query language, wherein the pattern query language includes functionality to search for at least one pattern in the target system.

17. A computer readable storage medium comprising software instructions for analyzing a target system, having software instructions stored thereon that, when executed by a processor, are configured to:

obtaining a characteristics model;

generating a characteristics extractor associated with the characteristics model;

obtain a plurality of characteristics from the target system using the characteristics extractor, wherein the plurality of characteristics is associated with the characteristics model configured to define each of the plurality of characteristics in a particular domain, wherein the particular domain corresponds to a grouping of related characteristics, and wherein the particular domain comprises at least one hardware component and at least one software component, wherein there is a relationship between the at least one hardware and software components;

store each of the plurality of characteristics in a characteristics store using a tracking mechanism configured to track changes to target system characteristics in the particular domain over time;

generating a characteristics store application programming interface (API) associated with the characteristics model, wherein the characteristics extractor uses the characteristics store API to store each of the plurality of characteristics in the characteristics store; and

analyze the target system in the particular domain by issuing a query to the characteristics store to obtain an analysis result, wherein the query uses tracking information associated with the tracking mechanism.

18. The computer readable storage medium of claim 17, wherein the tracking mechanism comprises storing a time-based attribute associated with each of the plurality of characteristics in the characteristics store.

19. The computer readable storage medium of claim 18, wherein the time-based attribute comprises at least one selected from the group consisting of a timestamp and a target system version number.

20. The computer readable storage medium of claim 17, wherein the characteristics store comprises a first sub-characteristics store and a second sub-characteristics store.
