UML 2 in a nushell

• Based on a paper by Birger Møller-Pedersen,
  Øystein Haugen, Thomas Weigert.

2
The Acess System Domain a class diagram
Note there are no parts i.e. instances here
3
The context as a Collaboration
multiplicity
Connector
Role
Note there are no classes here, only a structure
of part properties called roles!

Collaboration diagrams

• A collaboration with three roles and three
  collaboration uses
• may define a service structure

• TypeA must be compatible with (the semantic
  interface) TypeX
• Compatibility means that the role behaviours must
  be contained in the total behaviour of the actor
  how is a semantic variation point in UML2

5
Behaviour can be in three places

• The collaboration itself
• The roles
• The context (scope) of the collaboration

The Taxi System with interfaces bound as
collaboration uses
This is a composite class with parts. Each part
shall satisfy the roles bound to it

Collaborations for interface definitions

Reusable definitions not bound to a system
