You will only find "unowned relationships" terminology in Google docs. This "unowned relationships" in the GAE/J docs is where you have a field that is a "Key" or a Collection/Map/array of keys. So no *real* relation, just some implicit relation by that "key". You have to manage these keys yourself, and you tie your code to GAE/J by using them.
JDO/JPA specs do not mention such a thing; they only refer to relationships ... "owned" relationships ... real relationships. This is where a persistable class has a field that is of a persistable type, or a Collection/Map/array of a persistable type. i.e 0-N related objects. JDO provides managed relationships to keep both sides of a bidirectional relation consistent (under some circumstances). -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
