I googled "The Alice Book, databases", and nothing came out, so I'm fixing mostly this part in my review.
In a word, if you are a DBA, you don't need this book and won't be able to understand 99% of it, but if you are database theoretician, this book is on your bookshelf already.
This book quite complete review of relational database science as of 1995. In many cases, when studying particular subject I get away with original research papers available at citeseer and elsewhere, but often I find that it's much quicker just to open the Alice book at the right place.
