Date on Database: Writings 2000 2006 captures some of the freshest thinking from widely known and respected relational database pioneer C. J. Date. Known for his tenacious defense of relational theory in its purest form, Date tackles many topics that are important to database professionals, including the difference between model and implementation, data integrity, data redundancy, deviations in SQL from the relational model, and much more.
Date clearly and patiently explains where many of todays products and practices go wrong, and illustrates some of the trouble you can get into if you don't carefully think through your use of current database technology. In almost every field of endeavor, the writings of the founders and early leaders have had a profound effect.
