    1. BK - Spring 2006 Software Design 1 Lecture 10 Other UML Notations Activity Diagrams Documenting workflows Basic Notation ATM Case Study: withdrawal use-case Packages and Subsystems Implementation Diagrams (very briefly) Component diagrams Deployment diagrams

    2. BK - Spring 2006 Software Design 2 UML Activity Diagrams Used to document workflows: Modelling business activities or systems Modelling activities within/between use-cases Detailed description of operations in classes Similar notation to UML statechart diagrams: Activities (action states) States Transitions

    3. BK - Spring 2006 Software Design 3 Activity Diagrams & State Diagrams Notationally, very similar Important to distinguish purpose/use State diagrams: behaviour of individual objects/components show state transitions triggered by events Activity diagrams: behaviour within systems/organizations transitions between activities (work flows)

    4. BK - Spring 2006 Software Design 4 Activity Diagrams: Basic Notation

    5. BK - Spring 2006 Software Design 5 Activity Diagrams: Decision Points

    6. BK - Spring 2006 Software Design 6 Activity Diagrams: Swimlanes

    7. BK - Spring 2006 Software Design 7 ATM Case Study: Workflow for Withdrawal Use-Case

    8. BK - Spring 2006 Software Design 8 ATM Case Study: Elaborated Use-Case Description

    9. BK - Spring 2006 Software Design 9 ATM Case Study: Activity Diagram for Withdrawal

    10. BK - Spring 2006 Software Design 10 Packages and Subsystems Package: a collection of model elements: grouping semantically related elements analysing system architecture hiding irrelevant detail on a diagram Subsystem: special sort of package: representing units of the physical system developing components of the design

    11. BK - Spring 2006 Software Design 11 Packages: Organising Model Elements

    12. BK - Spring 2006 Software Design 12 ATM Case Study: Layered Architecture

    13. BK - Spring 2006 Software Design 13 UML Component Diagrams

    14. BK - Spring 2006 Software Design 14 UML Deployment Diagrams

    15. BK - Spring 2006 Software Design 15 Summary Activity diagrams: Model workflows Transitions between activities Use-case modelling/business modelling Packages Group logically related units Implementation diagrams: Component diagrams document physical elements Deployment diagrams document hardware elements
