This may be a dumb question…I just got finished looking at all 250+ MGMT$ view definitions to see what they can do for me via the Information Publisher Reports that one can create in OEM. We have 13c btw…
Anyway, while I can determine the Target_GUID appears to be a primary relationship key amongst quite a few of the collection of views…why is there no ERD available that would actually show the valid relationships? There are plenty of other GUIDs and plain old IDs to ponder upon as well. It just floors me that I can't find a simple ERD for these views.
