How to make a connection between employees and orders?

Question

Hibernate

Good afternoon.
There is an Order object. There is an Employee object. Each Order corresponds to several Employees with different logical connections, for example, the author, controller, etc. Each Employee can be linked to several Orders and with different types of communication (in one order he is the author, and in the other he is the executor).
There is also a need to ensure that each order has at least an author, performer, etc.
How can this be implemented in Hibernate 4? As far as I understand, it is possible to make an intermediate entity that will link one object to another and have additional fields. But I don't understand how to guarantee the connection

Answer 1

2.

how to ensure connection

Hibernate is an ORM, nothing less, nothing more. It gives convenient object access to the data in the database. But Hibernate is not required to understand your business logic. Well, the relational database level cannot guarantee the presence of many-to-many relationships, it is logical that this cannot be done at the Hibernate level either. Accordingly, the answer to your question is that your business logic should guarantee the existence of a connection .

Answer 2

It's clear. This is the answer I was expecting
