　　．Streamlined Coverage. By retaining only the most commonly used content, the book is now more concise.Rather than preformatted online content, a Website provides updated content and links on a regular basis. Thenumber of references in each chapter is reduced. Deleting Chapter 5, and instead putting some content in Chapter 1, streamlines the introductory coverage of business intelligence and data mining. With this change, the reader can get an overview of the overall content through Chapter 1 – both decision support and business intelligence technologies. This overview can prepare a student to begin thinking about a term project in either area (should the instructor require it) right from the beginning of the term. Then the details of decision support systems are covered in Chapters 2-4, and business intelligence topics begin with Chapter 5. The chapters available as online chapters with the last edition were deleted, with some content incorporated in this edition directly.

Dave King (JDA Systems), a co-author of The Strategy Gap (a book on corporate performance management) contributed Chapter 9: Business Performance Management.
