Use Case Diagram

A Use Case Diagram is a visual representation used in software and systems engineering to show how users interact with a system. It focuses on the functional requirements by displaying different ways a system can be used.

These diagrams are part of the Unified Modeling Language (UML) and help clarify system behavior without going into technical details. Use Case Diagrams identify various types of users (called “actors”) and the specific tasks or functions (called “use cases”) they can perform within the system. In IT, they are valuable tools for planning, documenting, and communicating the scope of a system to stakeholders, developers, and business analysts.
