I work on an application that connect to database by hibernate (I use annotations). I have 2 entities (Department and Employee). Of course the Employee has one Department but the Department has many employees.
What I want is to be able to delete some Department without delete its Employees. (When deleting Department the hibernate should delete constraints that link some Employees to it without deleting the Employees).
