Posted by Sriram Sanka on January 19, 2012
C.J. Date, is an independent author, lecturer, researcher, and consultant, specializing in relational database technology. He is best known for his book An Introduction to Database Systems.This book does n`t deal with SQL statements .. But is all about between SQL and the Relational concepts theory in a mathematical way.How SQL departs from relational theory, the basic principles of relational theory etc…
This Book contains 12 Chapters .. you can find Exercises at the end of each chapter.I like the Appendix section of this Book.
Appendix A: The Relational Model
Appendix B : SQL Departures from the Relational Model
Appendix C: A Relational Approach to Missing Information
Appendix D: A Tutorial D Grammar

I recommend this book for all who works with SQL.

You actually make it seem so easy with your presentation but
I find this topic to be really something which I think I would never understand.
It seems too complicated and extremely broad
for me. I’m looking forward for your next post, I’ll try to
get the hang of it!
