In the DataBound premier, Roger is joined by Aaron and Chris from Extended Results to discuss a custom PowerPivot application they developed for Microsoft called Calendar Analytics. This free Excel 2010 / PowerPivot app can be used to do some very useful analysis on your Microsoft Exchange calendar information whether it's hosted on-premise or in Office 365. This app is getting a lot of buzz and is a great example of how to deliver useful analytics to the average working professional with familiar tools they use every day.
If you want to learn more about PowerPivot, check out the SQL Server 2008 R2 Business Intelligence Training Course on MSDN. In particular, check out the last unit named Introduction to Self-Service Reporting and Analysis with SQL Server 2008 R2.
