This Education Management System Activity Diagram describes the flow of activity through a series of actions. The activity diagram is a critical diagram for explaining the system. An activity diagram depicts the overall control flow. We will learn how to draw an activity diagram for a project involving a student information system or a student management system. The School Management System UML Activity Diagram also gives programmers fresh ideas and guides them through the system development process. Students and School Faculties are key users in developing an activity diagram for the School Management System. Building interactions and activities in the system will be much easier if you know who the system's users are.
