Presentation Transcript

  1. UML Diagrams:Sequence DiagramsDynamic Analysis Model

  2. Sequence Diagrams • Depict object interactions in a given scenario of a given Use Case • Specify the messages passed between objects using horizontal arrows including messages to/from external actors • Time increases from Top to bottom

  3. Sequence Diagrams • Sequence Initiation

  4. Sequence Diagrams • Identify objects needed to support use case, determine sequence of internal events following the external initiating event • Diagrams that are not initiated with an external actor represent only a partial sequence • Partial sequence diagrams should clearly identify the actor initiated sequence diagrams from which they are launched

  5. Sequence Diagrams • Messages specified on interactions can be synchronous or asynchronous Synchronous call

  6. Sequence Diagrams Asynchronous call

  7. Sequence Diagrams • Display operation names on call arrows

  8. Sequence Diagrams Compound and Simple Iteration

  9. ‘included’ sequence diagrams

  10. Showing alternate behavior in a sequence diagram

  11. Showing Extension Point

  12. Specifying Timing Requirements
