I have a question about this. Coming from WebObjects/EOF, I do not

recommended to always include an inverse -- I do it in CoreData
just to get rid of the warning bu it I read that warning and I'm
like "I know. 'Cause I didn't make one 'cause I don't need one."
but the compiler doesn't care what I think :)
Core Data uses the inverse relationships to maintain referential
integrity. I suppose EOF can use foreign keys for that.
Is there any advantage to using unidirectional relationships?
