I'm not sure you have a joined-subclass relationship. That is, by definition a joined subclass has the same ID as its parent class. For example, you might have a Person entity stored in your database for generic "people" information like name/age/etc and then an Employee subclass entity which is stored in a different table and holds data like position, salary, and dates of employment.
So an Employee is a subtype of Person and to get the full "Employee-Person" object, you must join the two tables on their primary keys (e.g. SELECT * FROM Employee INNER JOIN Person ON Employee. Employee_id = Person. Person_id ).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
