Abstract

A method and system for creating and manipulating database files comprises a plurality of database files (19, 23, 50) and an object maintenance module (26). The database files (19, 23, 50) may generate database objects. The object maintenance module (26) may automatically generate a batch execution file (42). The batch execution file (42) may automatically execute the database files (19, 23, 50). In another aspect of the invention, the method and system may comprise a first database environment (22, 24) and a migration module (36). The first database environment (22, 24) may include a first set of database files (19, 23). The migration module (36) may automatically generate a second set of database files (50) from the first set of database files (19, 23). The second set of database files (50) are for use in connection with a second database environment (48). The migration module (36) may transfer the second database files (19, 23) to the second database environment (48).

Claims

1. A database system comprising:

a plurality of database files operable to automatically generate database objects; and

an object maintenance module operable to automatically generate a batch execution file, the batch execution file operable to execute at least two of the database files.

2. The database system of claim 1, wherein the object maintenance module is further operable to automatically arrange an execution order of the database files executed by the batch execution file in accordance with a predefined priority scheme.

3. The database system of claim 1, wherein the database system is operable to automatically stop execution of a database file being executed by the batch execution file in response to an execution error.

4. The database system of claim 3 wherein the database system is further operable to receive edits of the database file.

5. The database system of claim 4 wherein the database system is further operable to resume execution of the database file.

6. A method for generating a database batch execution file, comprising the steps of:

receiving selections identifying a plurality of database files operable to automatically generate database objects; and

automatically generating a batch execution file operable to execute database files.

7. The method of claim 6 and further comprising the step of executing the batch execution file.

8. The method of claim 6 and further comprising the step of automatically arranging an execution order of the database files executed by the batch execution file in accordance with a predefined priority scheme.

9. The method of claim 6 and further comprising the step of automatically stopping execution of a database file being executed by the batch execution file in response to an execution error.

10. The method of claim 9 and further comprising the step of receiving edits of the database file.

11. The method of claim 10 and further comprising the step of resuming execution of the database file.

12. A system for generating database files, comprising:

a database object foreign to the system; and

a batch schema generation module operable to automatically generate a database file, the database file operable to regenerate the foreign database object.

13. The system of claim 12, wherein the database file comprises a first database file and a second database file, the second database file operable to execute the first database file to regenerate the foreign database object.

14. The system of claim 13, wherein the first database file comprises a database definition language file.

15. The system of claim 13, wherein the second database file comprises a UNIX script file.

16. A method for generating database files, comprising the steps of:

receiving a selection identifying a database object foreign to a system; and

automatically generating within the system a database file operable to regenerate the foreign database object.

17. The method of claim 16, wherein the step of generating the database file comprises the steps of:

generating a first database file operable to regenerate the foreign database object; and

generating a second database file operable to execute the first database file.

18. A system for migrating database files, comprising:

a first database environment including a first set of database files; and

a migration module operable to automatically generate in a first staging directory a second set of database files from the first set of database files, the second set of database files for use in connection with a second database environment, the migration module further operable to transfer the second set of database files from the first staging directory to a second staging directory in the second database environment.

19. The system of claim 18 and further comprising a file management system associated with the second database environment, the file management system operable to store a copy of the second set of database files.

20. A method for migrating database files, comprising the steps of:

receiving a selection identifying a first set of database files in a first database environment;

in a first staging directory, automatically generating from the first set of database files a second set of database files for use in connection with a second database environment;

transferring the second set of database files from the first staging directory to a second staging directory; and

transferring the second set of database files from the second staging directory to the second database environment.

21. The method of claim 20 and further comprising the step of copying the second set of database files into a file management system associated with the second environment.
