Use case diagrams are used to show the various types of users on a system and the different ways that they interact with that system. They provide a graphical, simple representation of what your system must actually do.
The four basic parts of a use case model are actor, use case, system boundary, and relationships between actors and use cases. Actors are users or systems interacting with the system, use cases represent user goals or tasks, the system boundary defines the scope of the system, and relationships show how actors interact with use cases.
Use Case diagrams are behavior diagrams of UML used to describe a set of actions (Use Cases) that some system or systems (Subject) should or can perform in collaboration with one or more external users of the system (Actors).Each Use Case describes a unit of complete and useful functionality, some observable and valuable result that the subject provides to its users (actors)or other stakeholders of the system.Example use cases for bank ATM are: Withdraw Cash, Make Deposit.Use case diagram for ATM could show users of ATM, some or all of use cases, boundary of the system.
