Very important point highlighted by Chuck. EOF is very efficient in
maintaining all types of relations including recursive. You must
becareful of cyclic reference as it may lead into stack overflow
situation. Also make sure your model should care of the delete rule
otherwise... I just deleted my account but the whole network is
gone :)
I think wonder would have provided something to avoid cyclic fetch.

I think that should be fine. You might want to plan out how you
are going to qualify this for fetches.

Is it possible for EOF to support a reflexive relationship back to
the same Entity with the same relationship property name through a
flattened many-to-many?
Think of a User entity in the case of LinkedIn where users are
"linked" to other users:
User <---->>Connection<<---->User
Connection is the flattened (EOGenericRecord) m:n table with only
the foreign keys as its two primary keys. User.connections simply
returns all the connected users.
I'm imagining that you'd link them up like this:
userA.addObjectToBothSidesOfRelationshipWithKey(userB,
"connection");
Any one with experience/gotchas doing this? (No inheritance
involved.)
Thanks,
Joe
