Handling many-to-many relationships in Core Data

[Apocryphon]

Hey all,

I currently have this schema:

Company <->> Catalog <<->> Product

That's right, Catalog and Product have many-to-many relationships with each other. Right now I only have these three entities, as it seems like a fourth join entity is unnecessary according to the documentation. Is that correct? Are these all the entities I need, or should I create a "join" entity to mode the joins between Catalog and Product?

Unless I have misunderstood your question, the answer is: no, you don't need another entity to manage the relationships.
