Class Diagrams Perspectives

• Conceptual
• Draw a diagram that represents the concepts in
  the domain under study
• Concepts relate to classes, but there is often no
  direct mapping
• Conceptual model drawn with little or no regard
  for the software that might implement it.

3
Class Diagrams Perspectives

• Specification
• Focusing on the interfaces of the software, not
  the implementation.

4
Class Diagrams Perspectives

• Implementation
• Classes that will directly map to software are
  designed.
• Specific attributes methods are defined.
