Abstract
Use case diagrams work by describing the interaction between the user and the system through a story about how a system is used. Use case diagrams consist of several elements, namely actor, case, system, association, include, and extend. Use case diagrams are very useful for understanding how the system works and how actors are involved in the system. The sequence of steps that explains the relationship between the user and the system is called a scenario. Each scenario describes a sequence of events. Each sequence is initialized by a person, another system, hardware, or a time sequence. Apart from that, a use case is also defined as an abstraction of the interaction between the system and actors. Use case diagrams describe the expected functionality of a system. The emphasis is on ^what^ the system does, and not ^how^. A use case is a specific job, in this case for information system services to students at the faculty of engineering Universitas Negeri Medan
