Thanks Allan for the input - I guess I didn't specify enough details. I am looking for some type of tool/report that
isalready done. We have nearly 1000 tables, over 300 functions to look at a little over a day to provide the answers
(allwithout dropping any other tasks, of course). I had considered the trigger idea, and may end of doing it anyway
andjust working later, but thought I would check for a "ready-made" solution first.

Writing an audit trigger for the operations you'd like to monitor
(then assign it to all your application's tables) to perform the
auditing may be one easy way of doing so, this trigger would log the
operations to some other table.
