The correct approach is using different class for ViewModel and different for a persistance (entity). The usual reason is that you often need to send some additional data to a view (for example data to fill drop downs, data to disable some fields etc.), use different validation or show only subset of an entity.
Usually I have my View Models in the Models folder, and my Domain Models in the ORM Layer.
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.
