On the slightly more intermediate level to db design would be:
http://www.therationaledge.com/rosearchitect/mag/archives/9904/RATL-2.PDF
It is written from the perspective of Object Oriented Programming, so it
might be a better starting point for those with more OO experience.
Especially useful are points on:
