Thanks for the reply.
my question is regarding the component diagram, I have been reading about component diagrams for the past one week and all the sources contradict the information.
In my component diagram I am showing packages which contain components, but these components are shared between packages, for example in presentation tier I have 3 packages each containing components, and I have two components which are in all three packages in paresentation tier. Is is ok to that components are shared between packages?
thanks a lot
