UML modelling: Let us consider the following Learning Management System $($LMS$)$ description:

The LMS allows administrators to create, modify and delete courses. Learners can search course catalog to find specific courses and associated materials using keywords and titles. Each course has a title, a description, a duration, prerequisites $($when applicable$).$ Additional resources $($syllabus$,$ course preview videos, slides$)$ can be attached to course content. Learners can request enrollment on a course or cancel their enrollment. Learners can view their completed courses. The administrator can restrict content availability to specific date ranges. Learners can 'star$-$rate' content. The LMS should support all modern browsers and should be easy to use. Learners can use their mobile devices to upload their own videos or photos into the LMS$.$ Administrators need to approve new content added by learners.
