So I'm ok with relational theory, I think, and I know OO pretty
well, at least from a programmer's viewpoint.
But I'm unsure about this table inheritance thing. What is the advantage
of using inheritance over having a staff table with the staff columns
and a FK into the contact table? What are the disadvantages? Can anyone
point to some literature on this?
