What are all these databases with funny names? I help support SQL Server installation that hosts SharePoint and various related services. I never really looked at the database side of things until today when I noticed a whole bunch of databases with what look like GUIDs appended onto the database name. Can someone explain what these are? I tried to google for it but I didn't know what to google for and nothing came up from obvious google searches.
Sharepoint System Databases. And they are pretty self explanatory, or? Search service, secure store, session state - easy to understand.

THe rest is a GUID that is used in case multiple instances are installed - the Guid makes the database name unique.
