Den "SQL Server 2008 R2 Update for Developers Training Kit (January 2011 Update)" habe ich irgendwie verpasst. Der neue Content kommt mir allerdings auch gar nicht so neu vor. Möglicherweise ist das nur ein Update von SQL Server 2008 auf R2:

New Content: Build Your First Microsoft BI Solution with SQL Server 2008 R2
This update includes a rich new set of content designed for developers who want to learn how to build their first Microsoft Business Intelligence solution with SQL Server 2008 R2. Microsoft BI solutions leverage your existing technology investments in .NET, SQL Server and Office to develop rich integrated reporting and analytics experiences that empower users to gain access to accurate, up-to-date information for better, more relevant decision making. This content is a complete training course that contains eleven units covering all the key aspects of Microsoft BI solution development. You can find it by navigating to the Getting Started – BI Developers page. Here is a summary of what’s included:
31 presentations (PowerPoint slides, videos and transcripts included)
27 demos (installer scripts, videos and transcripts included)
12 hands on labs (installer scripts included)

Für Einsteiger in das Thema dürfte sich das aber dennoch lohnen. Hier ist der Download.
