Entity Framework Model Multiple Table to Single Entity

Question

I've two tables named Modules and Privileges which are related by a foreign key relationship as shown below:

_{(source: baburajpb at sites.google.com)}

I'd like to model Module and Privilege by adding ModuleName to Privilege. Later I'd be interested in creating a derived class (Menu in the illustration) from Privilege by adding a discriminating condition on ModuleName. Is this possible using Entity Framework?

Can you map multiple tables to a single entity type? Sure, that is supported. However, you cannot use a mapped field of the table (ModuleName) as a discriminator column for table per hierarchy mapping. The discriminator column must be used as a discriminator alone, and must not be mapped into your client schema.
