This depends a bit on what you mean with a model (just one relation, or a
set of relations) and embeddable (you want to implemente the relations in
one relation, you want to have an homomorphism from a relation to a
relation, et cetera). So could you expand a little bit on that, and perhaps
also indicate which text you are using to learn from? Then we might be able
to help you a little more.
