Maybe I made something wrong...

This is my "last" version of the model:

Entity Prodotto

Entity ProdottoPrivato

PNG image




Prodotto owns and propagate key to prodottoprivato.

The problem is... Prodotto needs ProdottoPrivato and prodottoPrivato needs prodotto..
So I created a "loop"..

ProdottoPrivato and Prodotto have a 1-to-1 relation
I can't create a Prodottoprivato without a Prodotto, but I want to do the inverse.
The PK of prodottoPrivato is the PK of Prodotto.

I don't know how to manage this..

Francesco
