Query: A gem

Whew. This is an outstanding book. It is simple and straightforward and explains complex concepts in an accessible way.If you want an excellent overview of databases, this is the place to start.Some examples:The chapter on Integrity (Chapter 16) instantly and lucidly gets the point across. I was a convert after reading the first 4 paragraphs.The exceedingly-simple ("yet-so-few-others-do-it") chapter breakout of Tables, Forms, Queries and Reports. Each chapter is its own "little-world" untouched with non-related ideas. The authors tie them together later. Extremely well executed.Excellent and I mean *excellent* typography and layout. The paper is white and high quality. The book is smallish in size and is readable, flippable and portable.This book does it right, in every way.
