RE: Journaling question.....

["Nelson, Jim (RCIS)" <Jim.Nelson@xxxxxxxxxxxx>]

I agree.

It's not that anything is 'missing' from the journal concept - just the
opposite.  It can be overkill

If you want to track specific information, and want to be able to quickly
get to that information, triggers writing to an audit file is very
effective.

If you need:
*       full-blown tracking of every row of every table, 
*       the ability to re-create any transaction, 
*       and the effort (in programming and retrieval time) is not an issue

Then by all means use journals.
