Aah, this is the point.. I am talking about. - The example I gave earlier is an unowned relationship ryt? *"Role can exist without user, user can exist without role, but user can have one or more roles"* > You have references to real objects so its a real (i.e "owned") relationship. If I store real references instead of Keys' does it become *Owned*, and If I store keys instead of *references* does it become *unowned* !!!. Then why would I take the trouble of unowned, I will store real references for all the relations, and all is well. - The question is, *When I must use Keys (unowned) instead of references, otherwise datastore will not support/handle it and through exception or whatever.* The answer to above question will implicitly explain "What is unowned relationship" and what is "unowned relationship is not supported"* Thanks SN On Sat, May 1, 2010 at 9:46 PM, datanucleus <andy_jeffer...@yahoo.com>wrote: > > *Google says "unowned relationship is not supported"* > > What does it mean? *How datastore identify that *it is unowned > relationship**? > > No idea.
