Average Reviews:
(More customer reviews)As I was reviewing this book for a class I was teaching on the subject, I could'nt help but think the author's effort was rushed. This book would be good for someone with a strong data modeling background who wants a new perspective. It is a poor choice for novices to the field. Explanations are lacking in clarity. Book is poorly organized. Check out Inside Relational Databases, Whithorn.
