Thanks, Sergey, Mike and Cindy. That's actually a question in the test. It doesn't specify a back-end. Would the same SQL be other databases (Access, VFP - obviously, it would, Oracle, etc.) complaint?

Also sorry for unrelated question, but could you please give me a good link for UML (introduction)?
