This book is the next version of the very popular "Pure SQL" series from AlphaPress. As always, the primary goal of the book is to provide the database professional with solutions to problems in everyday business situations. For this purpose, the author is following user newsgroups for years where multiple business problems are posted. That is why all the solutions in the book are business related and most often answers to actual problems faced by professionals. The second goal of this book is to help people who want to learn SQL from the ground up. For this reason the author included in the beginning of each chapter some simple but not simplistic examples so that the novice can be gradually introduced to the concepts of SQL and become an expert. If you need to teach Access SQL in a class environment, you might want to consider the book "Access SQL Comprehensive: version 2010" from the same author. Access 2010 Pure SQL is not a book from a smarty to smarties. It is a pragmatic book that will save you time by giving you answers to common business scenarios. For instance, it will explain to you very well what referential integrity is, how we use it, and why it is important for business. It will explain cross-tabbing and its significance for business analytical tasks. However, the book will not bother with teaching you relational algebra and the connection to SQL; it is not intended to waste a second from your time.
