Having been introduced to this book back at edition 5, the only regret I have is that I bought the paperback version of the book. Earlier reviews highlight the academic style of the book; whilst I would agree that Date tends toward a more formal use of the English language, his verbose style does reduce the use of a dictionary and jotting pad! Date writes in a way that allows the first time reader to simple read, concentrating on the issues at hand rather than trying to decipher the word as is so often the case with Grady Booch!! Be aware though this this book does cover everything from the beginings of databases systems, the reasons why they look the way they do today and some interesting ideas for the future - assuming we all have a Cray to run the systems on!! Each chapter is well thought out, ideas being built upon, with a consolidation at the end. If you are using this book as your class text book, the teacher will have to understand their subject properly. Date writes for the technically minded computer scientist not the layman. If you are new to computers and the world of databases especially, take a deep breath first and work slowly. This is no 'Dummies Guide to Databases', but then if you want an in depth knowledge you have to read about the subject in depth. Quite simply the only reference book you will ever need for Vendor-Independant database theory!
