When I had to create my first data model for an entire system, I instructed myself with this book and "Data Modeling For Information Professionals" by Bob Schmidt.

This book is excellent. The subject matter is advanced but still easy to read and understand.

I have many books on data modeling but this one is probably the most understandable. The examples are well-formed and many diagrams are provided along with written explanations.

I have found this book very useful in practice and it has served me well.

I'd recommend this to any intelligent professional who is moving into the data architect role,...
