RE: Whitepapers on Triggers
Since we are in the medical records business, we too have the same guideline. What we do, is create an exact table replica (we call it an archive table and it does not have constraints) to which before every insert and update on the primary table, sends the row data to the archive table. It stores the modifier and sysdate as well, so we have a complete history of revision. We don't allow deletes through users, only through dbas so that we can audit removals. Doing it this way eliminates that possibility of the fudge-factor on revisions/deletions. And when you are audited---it is a wonderful thing! lc -Original Message- Sent: Wednesday, November 13, 2002 11:49 AM To: Multiple recipients of list ORACLE-L This is for FDA regulation compliance.

RE: Whitepapers on Triggers
We have journal tables that mimic every table in our database. Every Insert, Update or Delete (we allow user deletes) gets the row written to the journal table along with a timestamp and the Oracle userid.

RE: Whitepapers on Triggers
That is exactly what my design would be given the option. Thanks for concurring. I have also been asked if the trigger can fire off a pop-up box in the app to ask for a reason for change that needs to be in the audit record as well. Yeah, really... that's what they want. Another option suggested for tables with heavy updates is to record the full insert and only the column deltas on updates. Okay, lets compare all 87 columns to see if the new value is the same as the old value. Just throw all kinds of junk in the trigger so it effects its performance. My origianl question was for any links to whitepapers on trigger devlopment. Thanks... Steve --- Lisa R.
