Thanks for the reply. Yes, ORM, in this case, meant Object Relational Mapping.

We are talking about new projects and new databases. Although actually, we've had databases and projects running, but the development architects have decided to toss it all in favor of this new approach.

Your statements coincide well with the research I've done so far. Do you have anything more quantifiable about problems with performance because of the object designed database? I'm not questioning you on that issue at all. I'm assuming it to 100% true. I just wanted to be able to present some math when we sit down for our discussions on this. Same question applies to the issues around reporting.

Do you have any other quantifiable problems around code maintenance, database maintenance, production troubleshooting...? Something I haven't thought of?

Thanks again for the response.
