Activity Diagram for Online Examination System

An Online Examination System Activity Diagram is a plan that helps with the development of a system. It shows the system’s behavior in terms of responding to its users or clients. This also gives the programmer ideas and guides them throughout the system’s making.

The users that are essential in creating an activity diagram for an 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 users. 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?

To have a clear understanding of it, let me tell you its purpose and role. The system must include an activity diagram so that programmers can determine how the software should interact with its users.

It is because the activity diagram guides the programmer in creating the software and its must-have behavior. So if you want friendly and effective or easy-to-use software, then you must also complete the activity diagram.

Activity Diagram Symbols:

Before we create the activity diagram of the Online Examination System, you must first know the symbols used to make it. And here are the symbols used in the activity diagram.

The given Activity Diagram samples for the activity diagram for online examination system are here. They will give you ideas on how to interact with the system.

  1. Designed Activity Diagram of Online Examination System for Examinee’s Side

    In the Activity Diagram shown, it illustrates the system’s behavior towards the examinee when doing an online examination. It also gives you an idea of how you would develop the system for the examinees’ side.

  2. Designed Activity Diagram of Online Examination System for Exam Provider Side

    Now the other activity diagram is designed for the exam provider side of the online examination system. It shows more detailed information on the interactions between the system and the exam provider.

    This design is meant to show and tell readers or clients that the system protects important exam records and that only authorized people can get to them. 

You should be informed that these diagrams can be modified to achieve your desired system behavior. You can also create your own unique system function to suit all of your clients’ needs. And if you want, you can copy all the ideas presented here, so you won’t need to create a new one.

You may also merge these diagrams if you want to make your activity diagram general. But you just have to make sure that the specificity is still there so your readers and system users understand the blueprint for online examination system development.


It is essential for you to know the diagrams used to design and develop the online examination system. This is due to the fact that, without it, it is impossible to create a fully functional system.

But if you create this activity diagram, you will know the possible inputs and scenarios that the system should process and perform. Not only that, but you will identify the processes that are required and connect them to the UML Diagrams.

By filling out the Activity Diagrams for each module or process, you will easily get to the system you want.
