  3. Diagrams • A diagram is a view into a model • Presented from the aspect of a particular stakeholder • Provides a partial representation of the system • Is semantically consistent with other views • In the UML, there are nine standard diagrams • Static views:use case, class, object, component, deployment • Dynamic views:sequence, collaboration, statechart, activity

  4. Sequence number

  5. Collaboration Diagram“who sends to whom” • Captures dynamic behavior (message-oriented) – not “when”

  6. Collaboration Diagram • Captures dynamic behavior (message-oriented) • Purpose • Model flow of control • Illustrate coordination of object structure and control

  7. Example: Change Flight Itinerary (Use case description)

  8. Sequence diagram for making a hotel reservation

  9. Collaboration diagram for making a hotel reservation

  10. UML Statechart Diagram Automata:

  11. action

  12. Statechart Example: Login part of an online banking system. Logging in consists of entering a valid social security number and personal id number, then submitting the information for validation.

  13. UML Activity Diagram

  14. Example: Activity Diagram – work flow, operation • Captures dynamic behavior (activity-oriented) Building a house • Syntax not defined in UML • Semantics: • Evaluate expression • Send a method • Create or destroy an object activity Synchronization bars Parallel activities Change of state or attribute
