Abstract

A technique for creating a custom database is provided. A system description of a structure of a database is received. A structure for the custom database is generated based on the system description. In addition, a search engine based on the system description is generated to store and locate data in the custom database.

Claims

1. A computer-implemented method of creating a custom database in a data store connected to a computer, the method comprising:

receiving a system description of a structure of (a) said custom database, and (b) an object, wherein said system description defines a mapping of one or more abstract objects to a physical representation in said structure of said custom database;

generating said structure for said custom database based on said system description; and

generating program code based on said system description, wherein said program code includes a module that, when executed, stores said object in said custom database.

2. The method of claim 1, further comprising generating a user interface to access said custom database.

3. The method of claim 1, further comprising modifying said system description and generating a new structure and new program code that are transparent.

4. The method of claim 1, wherein said structure stores data to form a relational database.

5. The method of claim 1, wherein said system description comprises a markup language file.

6. The method of claim 5, wherein said markup language file comprises an extensible markup language (XML) document.

7. The method of claim 6, wherein said XML document is created using a text editor.

8. The method of claim 6, wherein said XML file is created using a graphical user interface.

9. The method of claim 1, wherein said program code includes a module that, when executed, locates data within said custom database.

10. The method of claim 1, wherein said program code comprises a text search engine.

11. The method of claim 1, wherein said program code comprises a high level language.

12. The method of claim 11, wherein said high level language comprises an object-oriented language.

13. An apparatus for creating a custom database comprising:

a computer having a data store connected thereto, wherein the data store stores data; and

one or more computer programs, performed by the computer, for;

(i) receiving a system description of a structure of (a) said custom database, and (b) an object, wherein said system description defines a mapping of one or more abstract objects to a physical representation in said structure of said custom database;

(ii) generating said structure for said custom database based on said system description; and

(iii) generating program code based on said system description, wherein said program code includes a module that, when executed, stores said object in said custom database.

14. The apparatus of claim 13, further comprising generating a user interface to access said custom database.

15. The apparatus of claim 13, further comprising modifying said system description and generating a new structure and search engine that are transparent.

16. The apparatus of claim 13, wherein said structure stores data to form a relational database.

17. The apparatus of claim 13, wherein said system description comprises a markup language file.

18. The apparatus of claim 17, wherein said markup language file comprises an extensible markup language (XML) document.

19. The apparatus of claim 18, wherein said XML document is created using a text editor.

20. The apparatus of claim 18, wherein said XML document is created using a graphical user interface.

21. The apparatus of claim 13, wherein said program code includes a module that, when executed, locates data within the custom database.

22. The apparatus of claim 13, wherein said program code comprises a text search engine.

23. The apparatus of claim 13, wherein said program code comprises a high level language.

24. The apparatus of claim 23, wherein said high level language comprises an object-oriented language.

25. An article of manufacture comprising a computer program carrier readable by a computer and embodying one or more instructions executable by the computer to perform steps for creating a custom database, comprising:

receiving a system description of a structure of (a) said custom database, and (b) an object, wherein said system description defines a mapping of one or more abstract objects to a physical representation in said structure of said custom database;

generating said structure for said custom database based on said system description; and

generating program code based on said system description, wherein said program code includes a module that, when executed, stores said object in said custom database.

26. The article of manufacture of claim 25, further comprising generating a user interface to access said custom database.

27. The article of manufacture of claim 25, further comprising modifying said system description and generating a new structure and new program code that are transparent.

28. The article of manufacture of claim 25, wherein said structure stores data to form a relational database.

29. The article of manufacture of claim 25, wherein said system description comprises a markup language file.

30. The article of manufacture of claim 29, wherein said markup language file comprises an extensible markup language (XML) document.

31. The article of manufacture of claim 30, wherein said XML document is created using a text editor.

32. The article of manufacture of claim 30, wherein said XML file is created using a graphical user interface.

33. The article of manufacture of claim 25, wherein said program code includes a module that, when executed, locates data within said custom database.

34. The article of manufacture of claim 25, wherein said program code comprises a text search engine.

35. The article of manufacture of claim 25, wherein said program code comprises a high level language.

36. The article of manufacture of claim 35, wherein said high level language comprises an object-oriented language.
