ArcGIS 10.1 difference between 'AnalyzeDatasets_management' and 'Analyze_management'

Can someone please explain the difference between these two?

When running 'Analyze_management' on ArcSDE feature classes and checking inside the database for when the business and feature tables were last analyzed, the date/time I run 'Analyze_management' on them is correct.

When running 'AnalyzeDatasets_management' onArcSDE feature classes and checking the database the date/time for when the tables were last analyzed doesn't change as if nothing happened.

Setup is Oracle 11G/ArcSDE 10.1 SP1

Thank you
