RE: SQL help

I'm not sure I even agree with that. While the database would prevent you
from violating the RI constraints you may still do code-level RI checking
just so you can return more user friendly messages to your users. I don't
see the code being all that less complex if we have to monitor for each
possible RI violation in an update and then figure out what caused the
violation and return an appropriate message to the user.

I thing RI in code is still necessary, however I also put the RI in the
database so I can be assured that something outside my code (DFU, SQL, JDBC,
etc.) doesn't screw up my tables.
