Fundamentals of UML Diagrams
A diagram is the graphical presentation of a set of elements. UML has a lot of different diagrams. Read this section, and make sure you can differentiate between different diagrams.

3.8. Design Class Diagrams
We built a class (conceptual or Domain) diagram made using concepts having properties of these
concepts. No behaviour was allocated to any of these concepts. After creating collaboration
diagrams, we can progress the conceptual model, and build it into a true "Design Class
Diagram (DCD)". DCDs are based on the collaboration diagram. Attribute visibility is shown for
permanent connections. DCD is a diagram which we can base our final program code upon. We
can say that a DCD is a modification of a class diagram.
