How to represent a pair of paired relationships in a Database
I have 6 classes:
Fooqs &Foojs, both of which share a common core:Foo.
Barqs &Barjs, both of which share a common core:Bar.
Now, a Fooq always has a Barq, and a Foojalways has a Barj.
In C#, this is all easy to represent,
Foo and Bar are abstract classes, Bar has a Foo and Barq and Barj both have getters to wrap their Bar field and convert the type.It's not exactly beautiful, but it works nicely.
What is a sensible way to represent this in a (relational) Database?
And, how should I put together my Data Model so that EF CodeFirst constructs that Database model?
