SQL Server 2008 R2, like its predecessors, is more than a database engine. It is a
collection of components that you can implement either separately or as a group

two types of components—those that help you manage data and those that help
you deliver business intelligence (BI). Accordingly, we have divided this book into
two parts to focus on the new capabilities for each of these areas.
