Key is actually combination of 2 ids: parent and child. You can also use it for parent objects, but I like Long for simplicity. If you try using Long for child key Data Nucleus will complain very loudly :) Tomas The reason you have to use Key is mandated for the child objects.

I've read them all today and have found them extremely helpful. I just wanted to ask about the Key property. You seem to use it for some primary keys and you use Long for some others. Is there a reason for this? thanks Hi Tomas,
