[web2py] Re: Audit for all tables, independent of CRUD; and transaction rollback.

[Ross Peoples]

I don't know if there would be a good way to do this with any DAL/ORM. The 
best and most reliable way to handle this (and I hate to say it) might be 
using triggers in your database server. So that any change would trigger an 
audit action by the SQL server, which would write the change to an audit 
table. I had to do this for a Microsoft SQL Server 2000 application once a 
few years ago and it did the job.
