Modeling Dynamic Aspects of Systems

• Statechart
• Activity
• Collaboration
• Sequence
• Use Case

4
UML Statechart Diagram

• A statechart diagram shows
• state machine.
• flow of control from state to state.

6
UML Activity Diagram

• essentially a flowchart
• shows flow of control from activity to activity.

UML Collaboration Diagram

• an interaction diagram
• emphasizes the structural organization of the
  objects that send and receive messages.
• Shows
• a set of objects
• links among those objects
• messages sent and received by those objects.
• used to illustrate the dynamic view of a system.

UML Sequence Diagram

• emphasizes the time ordering of messages.
• has 2 features that distinguish it from a
  collaboration diagram.
• object lifeline
• vertical dashed line in the diagram.
• focus of control
• a tall, thin rectangle that shows the period of
  time during which an object is performing an
  action.

UML Use case Diagram

• shows a set of use cases and actors and their
  relationships.
• used to model the context of a system and to
  model the requirements of a system.

Modeling Physical Aspects of Systems

• Deployment
• Package

15
UML Deployment Diagram

• shows the configuration of
• run time processing nodes
• the components that live on them.

16
Deployment Diagram
17
UML Package Diagram

• shows organization and dependencies among a set
  of packages.

18
Package Diagram
19
UML Object Diagram

• shows a set of of objects and their relationships
  at a point in time.
• address the static design view or static process
  view of a system.
