How to Create a Data Flow Diagram Using the FREE Merit Modeler

A use case diagram shows how users (actors) interact with a system through specific actions (use cases). It includes actors, use cases, associations, and a system boundary. In the sample diagram, two actors - Regular User and Administrator - connect to four use cases: Log In, View Dashboard, Submit Request, and Approve Request. The Regular User performs the first three actions, while the Administrator handles the first two and the last one, approve request. The diagram illustrates system scope, user roles, and the functional goals each actor wants to achieve.
