Thread:There are many models (2)

Wait,to listen more..
Yes.This is what I have been waiting for. I mean, this has to be brought out that there are many and different models. There are two ways through which the interweaving and layering can be made possible. i) A thorough study of concepts ii) An exhaustive survey of working models which are actually in practice. I am gathering material for both purposes. Why not let us wait and listen to a few more persons whom I am pursuing to join us?
