Use Case Diagram

A use case diagram is a visual representation used in software engineering to depict the interactions between system actors and the system itself. It captures the dynamic behavior of a system by illustrating its use cases and the roles that interact with them. These diagrams are essential in specifying the system’s functional requirements and understanding how users will interact with the system. By providing a high-level view, use case diagrams help stakeholders understand the system’s functionality and its potential value.

See PlantUML Use Case Diagram for more information.
