UML Use Case Diagram


The use case diagram in the Unified Modeling Language (UML) is a type of static structure diagram that represents the user interactions with a system. This diagram portrays the different types of users and the various ways they interact with the system. In UML, the user is called actor and he can be human or an external system. The links between an actor and a use case are called associations. Use cases can be generalized, extended and included.
