Data is data in the long run. And you are right, "That said, you can approximate an IS-A relationship between table..." It's just a perspective that can hold true. Not that anyone should design with it in mind.
Long run: given a row, is-a relationships can be derived by single tables sometimes. :) Bart: God, Schmod. I want my monkey-man. In reply to Re^3: OO concepts and relational databases
