Question

I have this object graph, I want to map:

• abstract Account (username, password, …)
  • abstract Customer (shoppingcart, orders, roles)
    • IndividualCustomer (user data)
    • CorporateCustomer (different user data, company data)
  • Administrator (adminroles)

How can this be mapped against one table? (I know how to do this with an entity hierarchy that is only 1 level deep, just like in the docs, but this is different).

Anybody has an idea? I asked the same in http://groups.google.com/group/nhusers/browse_frm/thread/7a85cba0048c18d8?hl=en, but so far have not received a useful answer.

Answer 1

nesting subclasses is against the xml schema, so my guess is, it will not work. i probably would also have to nest the discriminator declaration, which also seems hackish.

and mapping it out flat… i pass a discriminator for an abstract class, that cannot ever be used because an abstract class cannot be instantiated. seems wrong, too.

but you are right, i will try it out some time. right now it seems like a better idea to me to let customer have an account, instead of being one.

thanks!
