NHibernate Conceptual Aggregate Roots

Question

I have a couple of entities that I want to treat as an aggregate. The problem is their association is conceptual rather than via foreign keys in the DB.

The schema I was given:
_{(source: robtennyson.us )}

My goal is to create an InventoryWeek class that I add inventory transactions to. So the inventory week obviously wraps FACIL_INVENTORY_WEEK and the transactions are added to FACIL_INVENTORY . So pulling this from the DB, I would get the week given the facility and date, and then I would want all of the transactions that have an INVENTORY_DATE within the week.

Is there a way to map this relationship in nhibernate? Or is there a better way to model this altogether?

Answer 1

You can map relations between tables based on non-primary-keys, but in a limited way.

To give some specific advise, you have to ask a more specific question. Try to map it and if something does not work as you expect, ask.
