Awesome feedback. As a side bar... Heh... no appologies for wanting to for wanting to form an opinion on some things on my own (which I still have to do) but it does sound like he's correct about the original rules not being so important anymore.

Thank you both.

I'd heard the book that Tom recommended wasn't so hot but it's one of the few things I can actually find that was written by Codd instead of being paraphrased. I'll see if I can dig up one of those cheap copies Tom was talking about.

Thanks again, guys.
