Question

: Draw a Class Diagram for a cloud-native Learning Management System (LMS). The structural model must robustly handle multi-tiered authentication (Instructors, Students, Administrators), hierarchical course architectures (Modules, Lessons, Assessments), and asynchronous enrollment tracking. (Note: Your diagram must explicitly utilize correct UML notation for multiplicities, visibility modifiers (+, -, #), directional associations, generalization hierarchies, and dependencies). State all underlying domain assumptions.

A cloud-native Learning Management System (LMS) can be modeled using UML class diagrams to represent the static structure of the system. The model supports multiple user roles, hierarchical course content, asynchronous enrollment processing, and secure authentication. Since a graphical diagram cannot be drawn in plain text, the following UML representation uses standard UML notation, multiplicities, visibility modifiers, generalization, associations, and dependencies. Underlying Domain Assumptions 1. Every user has exactly one authenticated account. 2. Users are categorized as Instructor, Student, or Administrator. 3. A course contains one or more modules. 4. Each module contains one or more lessons and zero or more assessments. 5. Students may enroll in multiple courses. 6. A course may have multiple enrolled students. 7. Enrollment requests are processed asynchronously through a queue/service. 8. An instructor may teach multiple courses. 9. An administrator manages users and courses. 10. Authentication is performed through a dedicated authentication service. ___ ________ ___ _________ _______ ______ ____ _____ ___ ____ ____.
