1. Introduction
1.1 Our Approach
This book adopts a unique approach which is based on using existing Data Models as the basis for designing new ones to meet specific requirements.
We have almost 800 Data Models on our Database Answers Website and they define our starting point –

We have used the Dezign Data Modelling Tool to create most of the Data Models in this book.
I chose it because it is powerful, flexible and affordable.
