Practical use of Flashback Archive in Oracle 11g

Question

Hi all,
<br>
<br>
With Oracle 11g, I have a conclusion on Flashback Archive and I'd like to know your opinion about it.
<br>
<br>
With the following limitation:
<br>
"For a table with Flashback Archiving enabled, you cannot issue the following DDL commands: <br>
ALTER TABLE (except adding a column), DROP TABLE, RENAME TABLE, TRUNCATE TABLE"
<br>
<br>
<b>I think Flashback Archive object cannot practically replace auditing mechanism we used to use in the database <br>
level by creating triggers on the audited table. What do you think?</b>

On the other hand most user defined auditing answers the 'what happened here?' question that auditors ask, but not the 'what did the data look like then?' associated question (except by hard graft).
