Every instance of a classifier realizing It describes different actions that a system performs in collaboration to achieve something with one or more users of the system. A use case diagram models different types of users interact with the system to solve a problem. inherits properties and behavior of the parent use case and may override the behavior of the parent. Specifically, a System Sequence Diagram (SSD) is a sequence diagram often used to show the interactions between the external actors and the system under design (SuD), usually for visualizing a particular scenario of a use case. Use cases allow to capture requirements of systems under design or consideration, business actor It should be enough to have actors, and if "stakeholders" have something else to add, the subject will be in a state in which no further inputs or actions are expected and the UseCase can be initiated again, This document describes UML 2.5 and is based on nor requirements by themselves. owns the contained use cases, but merely that the use case applies to that classifier.

Another example of such binding of a use case to the behavior represented by activity is shown below The purpose of use case diagram is to capture the dynamic aspect of a system. It models the tasks, services, and functions required by a system/subsystem of an application.
