UML case diagrams are an effective way of visualizing the overall system architecture of an inventory management system. They allow the user to see what actors, data, and processes interact within their inventory management system. These diagrams provide a logical structure of the software environment, making it easier to design and build the software. With properly designed class diagrams, users can easily identify and distinguish individual elements within their system architecture. UML case diagrams also help identify potential risks, thus enabling users to anticipate any problems that may arise during the development or maintenance process.
