I just finished reading Foundations of SQL Server 2008 R2 Business Intelligence written by Guy Fouche and Lynn Langit. Lynn Langit previously wrote Foundations of SQL Server 2005 Business Intelligence. Guy Fouche has written Pro SQL Server 2008 Analysis Services along with several other books. This particular book is pretty good at explaining how to use the Microsoft BI toolset, including SQL Server Reporting Services (SSRS), SQL Server Integration Services (SSIS), SQL Server Analysis Services (SSAS), and SQL Server Data Mining. I am glad I read it and wholeheartedly recommend it to anyone who is working with SQL Server. It provides ample examples for working with these products and it also delves into Report Builder, Excel, PowerPivot, and MDX. I like the organization of the book and the path it takes in discussing the different tools. The first subject it discusses is OLAP which is the subject that most readers probably are most interested in. So once you have a better understanding of OLAP and how SQL Server can address the subject area, then it moves on to using the other BI tools. The only thing I did not like about the book was that it does not cover Report Builder 3.0. It looks like a previous version of Report Builder. But, as far as I am concerned, that is ok, because I do not plan on using Report Builder. It also omits any discussion of shared datasets which are introduced by SQL Server 2008 R2 and it does not warn about updating the properties under certain situations (such as when deploying reports) when using SQL Server 2008 R2.
