The use case diagram in UML describes user requirements, describes system functions from the user's perspective, and points out the executors of various functions, emphasizing who is using the system and what functions the system executors are performing. It is mainly used in the requirement analysis stage to describe the functional requirements of the system to

requirements to the final implementation. In UML, use case diagrams are used to visualize the behavior of systems, subsystems, or classes, so that users of the system can better understand the purpose of these elements, software developers can also ultimately implement these elements. In reality, for users, how the system is implemented and how the internal structure of the system is not what they care abo

The use case diagram is used to describe the relationship between users, requirements, and system functional units. It shows a system functional model diagram that can be observed by external users. [PURPOSE]: help the development team understand the functional requirements of the system in a visual manner. The

Use Case Diagrams are used to determine the scope of requirements. These requirements are the basis for design and development. The use case diagram treats the system as a black box and understands the system from the perspective of external executors. As shown in Figure 12.
