At the top level, UML views can be divided into the following major areas:

  • Structural Classification: The things in the system and their relationship to other things.
  • Dynamic Behaviour: The behaviour of the system or other classifiers over time.
  • Physical Layout: The computational resources in the system and the deployment of artifacts on them.
  • Model Management: The organisation of the models themselves into hierarchical units.
