- Only a snapshot, not complete - Not truly dynamic |
|
|
What is an Interaction Overview diagram |
Provides high level overview of interactions within System. Shows dependencies and flows between use cases |
|
|
Strengths of Interaction Overview diagram |
- Shows dependencies between various sequences within System - Shows normal and alternative flows of sequence |
|
|
Weaknesses of Interaction Overview diagram |
- Not able to show "instance" level modelling - Confusion with referencing to other diagrams |
|
|
What is a State Machine Diagram |
Displays the flow of an Object interaction where the value of an Object changes. Described in States and Transitions. |
|
|
Strengths of State Machine Diagram |
- Represents lifecycle of an object - Represents dynamic aspect of System |
|
|
Weaknesses of State Machine Diagram |
