Being a computer science student I found it hard to understand the amount of theory behind Database Structures. This book provides very good guidance for solving non-trivial problems in storing complex data structures in a flat relational database. I found it very helpful and full of great ideas, which I have used in my web applications.
The book is a nice and easy read for an average user of the Internet or a middle level manager looking for information on data security. However it cannot be used as an academic source, since lots of opinion is very biased and rarely supported by fact or trustworthy sources. Nevertheless it is quite amuzing how the author pinpoints the formet USSR in almost every chapter of the book.
