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. Now we
have to tie one Oracle userid to one and only one user.

Please
respond to
ORACLE-L
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.
