Microsoft has posted 16 virtual labs online. The labs cover three major areas:
- Business Intelligence
- Mission Critical Operations
- Database Management
Those of us who are trying to jump start Self Service BI in our organizations should checkout the following three:
- Creating a PowerPivot Model and Report in the Excel Client
- Defining DAX Calculations with Microsoft PowerPivot for Excel 2010
- Exploring Power View
If you have not installed SharePoint or Microsoft SQL Server 2012 before, then these labs are probably your best option to play with the new features without having to spent a lot of time on standing up the enviroment.
