Fundamentals of Database Systems 6th (sixth) edition

Relational database theory, for a college level, Computer Science curriculum.I chose this book because it is a required text for an undergraduate database class. It presents relational database design from a theoretical basis. It provides an explanation, in depth, of the mathematical foundations of database theory. It is not a get started quickly, hands on guide to using SQL.This is an important text, and required reading for anyone looking for a deep understanding of relational database theory. It is not a hit the ground running, create a few queries quickly, how-to presentation. It is a serious work, and provides a serious understanding.

I didn't need to buy this, the class made it available online.
