Use Case Diagram Notations
Use Case Diagram consists of the following components:
- Actor: Actors are external entities that interact with the system. These can include users, other systems, or hardware devices. In the context of a Use Case Diagram, actors initiate use cases and receive the outcomes.
- Use Case: Use cases are like scenes in the play. They represent specific things your system can do.
- System Boundary: The system boundary is a visual representation of the scope or limits of the system you are modeling. It defines what is inside the system and what is outside.
