I read this blog post titled How to fail at ORM. Sometimes hearing what you should do to fail tells you exactly what you should do in order to succeed.
I haven’t used ORMs but usually people don’t seem overly excited to use them. I can’t comment out of experience, but this post sounds like some good reasonable advice.
Using an ORM sounds like committing to a relationship. As in any relationship, when committing to it, do it well, be in it for the long haul, play off each other’s strengths and keep your eyes wide open – after all, love conquers all 🙂
