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!

This is for FDA regulation compliance. The audit records need to show every change made to the source table in order of change.
WHile audit the table will show who changed the record, it won't show what was changed.
