title: Entity Framework map multiple tables to one entity
body: <p>I have a database with a table for active orders and one for inactive orders. I would like to model this in Entity Framework as one entity called Orders. I also need a way to determine if an order in this collection is active or not, preferably by having a status property on the entity that is set according to what table it is in.  Is there anyway to do this using Entity Framework 1. What about in Entity Framework 4?</p>
