NP-hard and classical problems are 50-50 in this book. I am wondering why they did not call it "Algorithm Analysis".

It covers almost every important aspect of modern DBMS within 1000 pages.

Leonid Libkin Springer http://www.cs.toronto.edu/~libkin/fmt/cover.jpg http://www.amazon.com/Elements-Finite-Theoretical-Computer-Science/dp/3540212027 This enlightening book changes my impression about the alice book, which turns out to be much more readable than ever.
