Database in Depth (Score:2)

Reading Date's book recently just reminded my of how much database theory I've forgotten since I was at college. He's right, of course, that the current set of popular database systems only implement a small part of Codd's original ideas[1] and that SQL is only a relational language in the very loosest meaning of the word.

But, of course, we all need to get some real work done. And you're going pay the rent a lot easier if you're an expert on SQL that you are if you're an expert on Tutorial D[2] :)

[1] If this kind of stuff is interesting to you then it's worth going and reading Codd's original paper [acm.org].

[2] Except, perhaps, if you're Chris Date.
