    Not sure I'm understanding. Account, Order and Address should all be classes (possibly entities), and either encapsulate, or have a factory or manager type object that encapsulates; their construction logic, including DAL stuff. It seems like you're thinking about this from a data perspective, not an OO perspective? Why would you join orders to accounts? Assuming 1 account to n orders, each order is going to have an account ID of some sort, right? So Account maybe has a member _address and a method GetOrders() which populates List<Order>. When you go to manipulate, display, whatever your Account-Order-Account._address permutation, the OO relationships drive the logic ... ?

Specifics. Maybe I'm the one missing; I've never been able to grok

 abstraction by itself, I always need a realistic example.
 
 I gave one: suppose we go your way, class Account, class Order. Now we
 join orders to accounts to get orders with addresses filled in from
 accounts. Oops, no class. How do we solve that problem? Not a

 rhetorical question, I'm actually curious about the proposed solution.
