We are horribly confused by the terrible TECHNET documentation on PowerPivot in SharePoint. We love PowerPivot and want to use all of the features available in our SharePoint 2013 farm. However, we don't know if we need SQL Server STANDARD or SQL Server
BUSINESS INTELLIGENCE to use all of the features of PowerPivot in SharePoint 2013. Can anyone tell us which one is necessary and point to a clear explanation of what the difference is?
