Relation between Inv_ClientTasks and SWDPackage

Hi,

I need a report where I see the following informations:

Hostname - installed Software (including version, edition, service pack) -  packagename - package location

Actually I found the table Inv_ClientTasks for a lot of my needed Infos. Furthermore I found in SWDPackage the Package Location.

Unfortunately I dont find any relation bewtween Inv_ClientTasks and SWDPackage.

Does anybody has an idea?

Maybe a better table / view to get all these informations?

These informations above mentionend are a small extract of my needed infos :-)

Where I can find a database diagram where I can see all relations between the tables?

Thanks,

Patrick
