Free Online E-Learning System Data Flow Diagram
This Data Flow Diagram (DFD) for an Online E-Learning System is designed to visually model the processes and data exchanges related to student assignments and grading. It is an essential analytical tool for system analysts, software engineers, and e-learning platform developers. The workflow begins when the Student submits an Assignment. This data flows through processes like Download Unmarked Assignment and Mark Assignments by the Tutor. The process concludes with the Record Marks and Comments step, which leads to the student being able to Retrieve Marked Assignments. The resulting DFD provides a clear, documented view of the system's operational logic, ensuring efficient, accurate management of student academic progress.
