Use case helps identify messages (operations and required information or data parameters) that bind objects and classes together.

Use Case scenarios, usually represented by sequence diagrams, involve the collaboration of multiple objects and classes.

Use cases can help manage the complexity of large projects by dividing the problem into major user characteristics (i.e., use cases) and specifying applications from the userвЂ™s perspective.

Because use cases are easy to understand and provide a good way to communicate with customers and users because they are written in natural language.

Use cases are powerful technologies to capture and document black box functional requirements.

The system boundary defines the boundary between the system and the outside world. Relationship between Participants and Use Cases System Boundary Use cases are usually initiated by users to describe the activities and procedures involved in achieving the goals.

Use cases describe how participants use the system to achieve specific goals. Actor can be a user or other external system. Use case diagrams contain four main components:ДЄctor are usually individuals who participate in the system according to role definitions. Use cases define interactions between external participants and the system to achieve specific goals. Describe a main event flow (main scenario) and possibly other abnormal flows (optional), also known as paths or user scenarios.Functional requirements -Model of interaction between system and participants.Use case diagrams have the following features:

Use cases consist of a series of possible interactions between the system and the user, which define the functions to be implemented and the solutions to any errors that may be encountered.ДЄlthough the use case itself may go deep into many details of each possibility (e.g., the flow of events and scenes), the use case diagram can help provide a more intuitive view of the system and a simplified and graphical representation of what the system actually must do. Use case diagrams can effectively identify and explain system requirements. Use case diagrams describe a series of actions or event steps and generally define the interaction between participants and the system to achieve a certain goal. Therefore, the use case diagram is to develop the correct system by capturing requirements from the perspective of users.

Use Case: ActorWhat do users want to achieveпј›.

The visual description of the use case diagram is as follows: Use case diagram consists of system, relevant use case diagram and participants, and connects them with each other.

Use cases describe how users use the system to achieve specific goals. ** For details, please refer to the legend of UML design on the Online Drawing website: ** Use Case
