    SQL ? Query excercies? Never been so easy before.

    Our university just suggested us to use this text book (only read it till Chapter 20 in class but umm found it so easy and enjoy reading it (even in free periods)that I read it till 25 th chapter. I found it interesting , faced some problems in the start but in my opinion it is cool and easy to understand in addition to that it contains a wide variety of References and Bibilography's. I really liked it.

    Describes HOW database systems should be implemented

    Date's treatment of database systems is heavily weighted toward the foundational principles of the relational model. If that is not what you are looking for, this text is not for you. If you want to learn SQL, get a good SQL book. If you want to play with MS-Access, by all means, do so. If you have a five-minute attention span, this book isn't for you. If, however, you wish to understand the foundational principles of database systems and what makes for a 'good' DBMS, this is the text for you. If you can't understand the theory in this book, you have no real business calling yourself a database professional. Prior to this time, I had avoided using DBMSs (as being one of the more boring aspects of computer science.) Spending six weeks wading through this book changed my mind on that. Date shows the beauty of the relational model clearly and precisely (I will grant that the emphasis is on precision rather than simplicity.) Date shows the flaws of SQL as well as its power. In this new 7th edition, more than in the earlier edition, he proclaims the way database sytems should be structured, rather than accepting the SQL status quo. He also points out clearly how the so-called object model really isn't a data model at all, and could lead us back to the 'bad old days' of ad-hoc DBMSs with no theoretical nderpinnings (and hence no verifiability.)
