Question

A client want you to develop an online education system to facilitate the students to attend their online classes. All of the classes will be scheduled by the admin staff. And, the teachers will be allowed to manage (create, modify or delete) their online classes list and other content with respect to courses as well as class sections. Only the admin staff will be able to manage the enrollment of students, and courses details. While the teachers can only update the course contents. You are required to automate the functionality of the system in order to provide a detailed summary to the admin staff that will help to monitor the classes by status (Delivered, Missed, or Rescheduled).

Keeping in mind the above scenario, please solve the following:

Define the stakeholders/actors involved in this online education system
Define core functionalities of the whole system
Draw a use-case diagram using any tool (Online / Offline)
