I knew what a database was before I read the book. I think that was all. Now I manage a student (a sophomore) who handles our Multi-University Research Initiative Relational Database-backed web site. It's not all Greenspun's input--but like 90% of the wisdom came from Greenspun's book. I bought all his suggestions (mostly because he justified them), and they all panned out. Get AOLserver, get Solid, spend lots of time on the data modeling, don't write anything in C, don't fork a cgi process every time you want to query the database--hang the database off the server... This could get long quickly. All I know (almost) about databases, I learned from Greenspun. But don't get me wrong; if you're an idiot, you won't appreciate the book--so don't buy it.
