Auditing is a definite overhead but the degree varies depending on what auditing is set up and how many transactions you have.
Auditing can tell you who did what to a table (IUD etc). What it will not do is store before and after values.
If that is what you want then triggers are required. Obviously if a new record is going to be written to an audit table every time a record in the master table is changed then that can cause significant database activity which will have an overhead on performance and possibly space as well depending on the volumes.
Another workround could be to use Logminer to check what a user has done and when. This is perhaps more suitable for a one off security check that a method of tracing every change by any user at any time.
Realy it is a matter of negotiating requirements v performance v implementation time/costs and identifying which solution (or mixture of the above) provides the necessary facilities

Subject: auditing tables
Hi all,
does anyone have experience in using Oracle's possibilities of auditing
a database ??
I am interested in performance questions i.e. is it a hughe loss of
performance
when auditing tables Inserts/Updates/Deletes. Should I use triggers instead
?
any hints (comments, websites, etc...) are welcome.
