However, the three classes are intended to match up with Database Systems: The Complete Book (which, in the interests of full disclosure, is written partly by my former advisor). If you want to learn the material from the second class, I would just read the book. I've actually read the book cover to cover, and I think it's one of the best textbooks for that purpose. There are tons of examples everywhere, it's pretty talkative, and there is very little pretension (insert Russell/Norvig complaint here). On the other hand, some portion of the Internet seems to take the opposite view (e.g., some people just view the talkativeness as repetition).
