Online Examination System Activity Diagram – is a designed blueprint that provides a big help in system development. It shows the system behavior in terms of responding to its users or clients. This also gives the programmer ideas and guides them throughout the system making.

The users that are essential in creating an activity diagram for Online Examination System would be the Examinees and the Exam provider. By determining the users of the system, it would be much easier for you to build the interactions and activities in the system. Then you will be able to foresee the behavior of the system towards its user. So you should be aware that your system must be user-friendly and effective for its users.

What is a Online Examination System Activity Diagram?

Additional Knowledge

The activity diagram works perfectly with the other UML Diagrams which were available also on our site.
