Study Notes
Interaction Diagrams
- Depict the interactions of objects and their relationships, including messages passed between them.
- Two types: Sequence diagrams and Collaboration diagrams.
- Used for modeling control flow:
- Sequence diagrams model control flow by time ordering.
- Collaboration diagrams model control flow of organization.
Sequence Diagrams
- Illustrate the ordering of messages according to time.
- Typically show the flow of functionality through a use case.
- Components:
- Actors: Involved in the functionality.
- Objects: The system needs these to provide functionality.
- Messages: Represent communication between objects.
Collaboration Diagrams
- Illustrate the structure of objects that send and receive messages.
- Directed graph using objects and actors as nodes.
- Focus on the roles of objects as they interact.
- Directional links indicate communication between objects.
- Links are labeled with appropriate messages, prefixed with sequence numbers for time ordering.
State-Chart Diagrams
- Show a state machine depicting an object's control flow from one state to another.
- Portray sequences of states an object undergoes due to events and responses.
- Components:
- States: Simple or Composite.
- Transitions: Between states.
- Events: Causing transitions.
- Actions: Due to events.
- Used for modeling objects that are reactive in nature.
