In the relational approach, by separating the rules and the data store, that is exactly where they are: BETWEEN the application and the data store.

Why did you do it: because I can. A lot of presentational application code has tabular structure. While there may be no need to share that (it is not user data, it is code) it is convenient to put it into something which has a track record of storing tables.
The content of the tables resulting from this practise (the use of the tables managed by the DBMS to contain application code) should be treated as what it is, part of the code: apply change management discipline, include the tables in packaged releases etc. Received on Sun Jun 20 2004 - 03:53:51 CDT
