Contrary to what is stated in the other review of this book I find it very useful. I suppose that guy is not interested in much more than how to write simple SQL in which case I can agree that there might be more extensive books...
However, if you are like me and want to know a little more than that this is a really good book on database system concepts. It explains how things work and why they work. The explanations of these concepts are supported by simple descrete mathematics notation. I really liked this book and I recommed this book to anyone who wants to know how databases work.
