The following is a line of code in an Application class. Employee is the POJO class. We are detecting a particular employee to be deleted using the EmployeeID. Is it possible to delete the whole schema of that particular employee only through knowing the employeeID? Here, employeeID is generated id.
All in all - what does session.get() does?
Employee employee =(Employee)session.get(Employee.class, EmployeeID);
session.delete(employee);

Deleting whole schema i would suppose you mean to say like employee has some other components inside the employee class like address and when u want to delete the employee it should get deleted too?

yes

You can use Cascade
