System catalogs should help, unless I misunderstand your question:

Hi All:

I have tables with different versions in the same schema.  Like 

T1a, T1b, T1c

T2a, T2b, T2c, T2d

....

...

etc.

I'm interested in documenting various version of tables, may be in excel sheet or may be in another schema in the database.  I would like to store information on table name, column names, column order, pry key column etc.  Also is there a way I can reverse engineer from the database itself.

Let me know if anybody any suggestion or format that they used.  I appreciate all your help and shall be suitably acknowledged. 

Thanks,
