This UML class diagram offers a structural view of a software system, detailing how different classes interact within the application. It includes the 'Role Class' for defining user roles, the 'User Class' for managing user information, and the 'Task Class' for task-related operations. The template defines attributes like name, email, and password, as well as operations such as add, view, and update for each class. This class diagram is perfect for educational content aimed at teaching software development, particularly in object-oriented programming and design courses.
