Category : Use Case Diagram

A use case diagram is a type of diagram used in Unified Modeling Language (UML) to represent the relationships between actors and the actions (or “use cases”) that they can perform in a system. The actors in a use case diagram are typically external entities that interact with the system, such as users or other systems. The use cases are represented as oval shapes and are connected to the actors by lines, with the arrowhead pointing towards the actor. Use case diagrams can also be used to show the relationships between use cases, such as inclusion or extension relationships. Use case diagrams are commonly used in software engineering to represent the functional requirements of a system.
