Source document framework for accounting systems

1. A computer-implemented method, comprising:

receiving an electronic communication comprising a source document having unknown processing requirements;

creating a new source document type to process the source document and preserve referential integrity in a database by:

utilizing a set of extension points in computer memory to create a source document header relation with source document header information and a source document line relation with source document line information for a previous source document type, the source document header information and the source document line information being operative to reference at least a portion of the source document for process logic that is specific for use with the previous source document type, and

defining the new source document type with a non-overlapping foreign key reference to the source document header relation; and

storing the source document in the database by using the source document header relation and the source document line relation to reference the source document in that database.

2. The computer-implemented method of claim 1 , wherein the source document header information including a source document header record identifier field and a source relation type field.

3. The computer-implemented method of claim 1 , wherein the source document line information including a source document line record identifier field, a source document header field, and a source relation type field.

4. The computer-implemented method of claim 1 , comprising receiving a request to create a source document of the new source document type.

5. The computer-implemented method of claim 1 , comprising storing a document header relation with document header information for a source document of the new source document type, the document header information including a source document header field of type source document header record identifier.

6. The computer-implemented method of claim 1 , comprising storing a document line relation with document line information for a source document of the new source document type, the document line information including a source document line field of type source document line record identifier.

7. The computer-implemented method of claim 1 , comprising providing a source document framework for referencing source documents of source document types in the database using non-overlapping foreign key constraints.

8. At least one computer-readable storage device comprising instructions that, when executed, cause a system to:

receive an electronic communication comprising a source document having unknown processing requirements;

create a new source document type to process the source document and preserve referential integrity in a database by utilizing a set of extension points in computer memory to create a source document header relation with source document header information and a source document line relation with source document line information for a previous source document type, the source document header information and the source document line information being operative to reference at least a portion of the source document for process logic that is specific for use with the previous source document type and defining the new source document type with a non-overlapping foreign key reference to the source document header relation; and

store the source document in the database by using the source document header relation and the source document line relation to reference the source document in that database.

9. The computer-readable storage device of claim 8 , wherein the source document header information including a source document header record identifier field and a source relation type field.

10. The computer-readable storage device of claim 8 , wherein the source document line information including a source document line record identifier field, a source document header field, and a source relation type field.

11. The computer-readable storage device of claim 8 , comprising instructions that when executed cause the system to receive a request to create a source document of the new source document type.

12. The computer-readable storage device of claim 8 , comprising instructions that when executed cause the system to store a document header relation with document header information for a source document of the new source document type, the document header information including a source document header field of type source document header record identifier.

13. The computer-readable storage device of claim 8 , comprising instructions that when executed cause the system to store a document line relation with document line information for a source document of the new source document type, the document line information including a source document line field of type source document line record identifier.

14. The computer-readable storage device of claim 8 , comprising instructions that when executed cause the system to provide a source document framework for referencing source documents of source document types in the database using non-overlapping foreign key constraints.

15. An apparatus, comprising:

a processor circuit; and

an application arranged for execution by the processor circuit, the application configured to provide services to a database, the application comprising:

a source document framework component arranged to:

receive an electronic communication comprising a source having unknown processing requirements,

create, for an enterprise resource planning (ERP) application, a new source document type from the unknown source document type to process the source document and preserve referential integrity in the database by utilizing a set of extension points in computer memory to create a source document header relation with source document header information and a source document line relation with source document line information for a previous source document type, the source document header information and the source document line information being operative to reference at least a portion of the source document for process logic that is specific for use with the previous source document type and defining the new source document type with a non-overlapping foreign key reference to the source document header relation, and

store the source document in the database by using the source document header relation and the source document line relation to reference the source document in that database.

16. The apparatus of claim 15 , wherein the source document header information including a source document header record identifier field and a source relation type field.

17. The apparatus of claim 15 , wherein the source document line information including a source document line record identifier field, a source document header field, and a source relation type field.

18. The apparatus of claim 15 , wherein source document framework component further operative to receive a request to create a source document of the new source document type.

19. The apparatus of claim 15 , wherein source document framework component further operative to store a document header relation with document header information for a source document of the new source document type, the document header information including a source document header field of type source document header record identifier.

20. The apparatus of claim 15 , wherein source document framework component further operative to provide a source document framework for referencing source documents of source document types in the database using non-overlapping foreign key constraints.
