I am testing SharePoint 2013 / SQL Server 2014 combination. I upload a PowerPivot Excel to PowerPivot gallery and do some testing.
I notice that when I delete the PowerPivot from the PowerPivot gallery, the database in PowerPivot SQL server is not deleted.
I uploaded the same PowerPivot several 4 times during testing, and now there is 4 databases in SQL server even tho I have deleted all PowerPivots from the gallery.
How are the databases deleted?
