Hi,

I have an order class which has a collection of OrderItem.
OrderItem has property such as Quantity, PriceSnapShot and a property of type CatalogItem which refer to an item.

So a CategoryItem can be in many OrderItem
and an OrderItem have one and exactly one CategoryItem.

It makes sense to add a many-to-one element in my OrderItem mapping file, right?

but do I have to put a bag element in my CategoryItem if I don't need to navigate from a CatalogItem to my OrderItem?

Thanks.

afaik, you should only model the relations that you want. So the answer would be: no ;-)

Thank you! :)
