Aside from sending raw SQL commands to insert the Employee minus Applicant properties fragment into the Employees table I believe it's impossible. You can either update or insert an entity. What you want is basically to update the base part of the Employee (or do nothing if nothing changed) and insert the derived part which is not possible.
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.
