Patrick,

In my opinion, data validation and other business logic belongs in the same
module that handles the database I/O.

I'd suggest following this link:

http://www.relational-data.com/products/rweb/docs/docframeset.htm

Then click the User's Guide Link, and browse through the lessons pertaining
to the Chat Server sample application.  It offers an implementation of M-V-C
design.
