An anonymous reader writes "I have deep experience programming in many languages, and I've some exposure to SQL through PostgreSQL. My math goes so far as trig and algebra, with a little statistics. So far, I've learned enough to be dangerous: mostly via other people's code, experimenting, the PostgreSQL docs, etc. I've been successful using the DB in various ways, but I know I am missing a great deal (and probably doing it wrong, at that.) When DB articles come up on Slashdot, I don't recognize a good deal of the terminology. What is the best way for a technical person to learn SQL/DB work using PostgreSQL? Books? Tutorials? I should mention I don't have local access to a university or people with DB knowledge; have to do this on my own, so books or the Internet are pretty much my options."
