Introduction

O

ur purpose in Introducing Microsoft SQL Server 2008 R2 is to point out both the new and the improved in the latest version of SQL Server Because this version is Release 2 (R2) of SQL Server 2008, you might think the changes are relatively minor—more than a service pack, but not enough to justify an entirely new version. However, as you read this book, we think you will find that there are a lot of exciting enhancements and new capabilities engineered into SQL Server 2008 R that will have a positive impact on your applications, ranging from improvements in operation to those in management. It is definitely not a minor release!
