Yes It is legal to have more than one entity for single table. This is the problem called Granularity.

Hope This is helpful!

What do you mean by own? A composition of P owning C using UML semantics? If so, you should have an unique constraint defined on the table, P is mapped to. In addition, you should map the property of P holding C, with cascade=”delete”. With all this in place, one thread should succeed in persisting C, owned by many threads in terms of having different Ps owning the same C. All the others should fail to commit, because of the unique constraint defined.
