Hibernate is a persistence API which is intented not to care about how data is stored in no matter what DBMS engine or XML files. It is a framework to persist your objects. But it does not stop there, since you can run queries (pseudo SQL or through Criteria API), what results altogether in fact in an objet oriented data storage.
It looks like you are trying to solve the wrong problem.
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.
