Decoupling into DAL and BLL - my concerns?

For your ui my suggestion is to have a dto (a viewmodel for those mvp/mvc people) hold the user's data and the corresponding list of documents.

I ran into the same thing in the past while creating my own custom data access layers. You want your objects to map one to one to your db, but many times you just need to write one off custom functions to retrieve inner joining data. I would not put these custom actions into their own 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.
