16.2. Definition: Design Class Diagram
As we've explored, the same UML diagram can be used in multiple perspectives (Figure 16.2). In a conceptual perspective the class diagram can be used to visualize a domain model. For discussion, we also need a unique term to clarify when the class diagram is used in a software or design perspective. A common modeling term for this purpose is design class diagram (DCD ), which I'll use regularly in later chapters. In the UP, the set of all DCDs form part of the Design Model. Other parts of the Design Model include UML interaction and package diagrams.
