Study Notes
Sequence Diagrams vs Use Case Diagrams
- Standard sequence diagrams display the progression of events over a certain amount of time.
- System sequence diagrams (SSDs) show sequences for specific use cases, providing more detail than standard sequence diagrams.
- Use case diagrams are a type of diagram that represents a user's interaction with the system.
System Sequence Diagrams (SSDs) and Use Case Model
- SSDs are a part of the Use-Case Model, which is a visualization of interactions implied in the use cases.
- The Use-Case Model provides a comprehensive view of the interactions between users and the system.
