core data structure?

Subject: core data structure?

Hi,

I was wondering if anyone could point me in the right direction?

I have 2 entities, product and order. At the moment they are linked with a many to many relationship as an order will have many products, and products may be in more than one order. My issue is that when I link them I cannot link quantities. For example, I may want to order 10 of a product in an order. I figure I need to split out the relationships, so I need a third entity, for example orderItem, which has relationships to both the product and order entities, but also has a quantity attribute.

Am I right here?

Many Thanks,

Amy Gibbs
