DAL/BLL and Client/Server: Should the client use BLL or DAL objects for presentation? Or maybe another layer (data transfer object?)?

It is not a good idea exposing 'inner objects' like objects used/returned buy the DAL. Better keep all inner objects hidden from the client and have a complete set of objects for client-server communication. It might be some extra work converting one object to another but will make upgrading the system much easier in case server and client don't upgrade together.

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.
