Ah yes, the famous database integration anti-pattern.

The fact that you have being practising "database integration" won't suddenly disappear just because you used a ORM. In fact I expect even worse database integration from your average ORM user, as people that uses ORM blindly often don't care (to their own detriment) about "silly issues" like data provenance or persistence mechanical sympathy.

At some point I expect the DBAs of such database integration nightmares will have to start handling stuff like column-level security and row-level security to prevent naive users from shooting themselves in the foot.
