I was keen from Day 1 to install SharePoint 2010 WITHOUT the GUIDs in the database names for the farm and service applications! That was possible through PowerShell but with the exception of ONE Service Application database – PerformancePoint!
Good news is that since SharePoint 2010 SP1 we now have a ‘DatabaseName’ switch parameter when creating a new PerformancePoint Service Application through PowerShell!
Type in: get-help New-SPPerformancePointServiceApplication -full
Specifies the name of the PerformancePoint Service database used for the service application.
Accept pipeline input? False
Accept wildcard characters? false
