Assignment $1$: Designing a System with OOP

Now, you are designing a system with the Object Oriented Programming$($OOP$)$ paradigm. The system can be used in any concrete scenario, like Course Management System, Student Management System, Library Management System, etc.

For example, for designing a Course Management System, you can decide the entities$($i$.$e$.,$ classes$)$ and functionalities $($i$.$e$.,$methods$)$ in such a system. Possible functionalities include course registration, course search, grade analysis, etc. You should design at least $6$ classes $($like student, teacher, admin, lecture course, etc.$)$ and leverage the features of OOP.

You are free to select other $$XXX$$ Systems and design at least $6$ reasonable classes. And you don't have to write the code to implement the management system.

To complete this task, you should provide a document $($less than $4$ pages$)$ describing your system design and related functions. More importantly, youMUST insert a UML class diagram to show the relationships among the classes in your system. You can use the Violet UML Editor, diagrams.net, or other UML tools.
