Online Examination System Sequence Diagram | UML

The Online Examination System Sequence Diagram is a UML diagram that shows the sequence of events that should be present in the Online Examination System.

Furthermore, this sequence diagram for the online examination system gives enlightenment and a guide to the programmers and developers on how they should build the system. The idea presented in a sequence diagram will improve the efficiency of the Online Examination System’s development.

Moreover, The idea of the online examination method is to assess students’ subject understanding. In comparison to the traditional pen-and-paper examination, such a technique avoids logistical issues and disadvantages.

How to create a Sequence Diagram for Online Examination System

Now, to create the sequence diagram for the online examination system, you must first be familiar with its symbols. This is to know how you would emphasize the whole content of your online examination system. With the symbol’s familiarization, you’ll then easily understand the ways of the system’s development.

Also, for a better understanding of system development, there are a lot of UML diagrams available on this site. Because aside from the system sequence diagram, there are still use cases, activities, and other essential diagrams needed.

Simple (UML) Online Examination System

Now in this article, I will be showing you the sequence illustration of the online examination system. This design will enlighten you on how the system and the actor should approach each other. This will also teach you how to develop the system to achieve its desired behavior.

Sequence Diagram for Online Examination System Design

The design that I will be showing you is a detailed illustration of the sequence of events that happen in the Online Examination System.

This carefully designed sequence diagram is able to show programmers and readers about the sequence of messages between the actor and the objects.

As you can see in the illustration, the conditions and interactions are emphasized. These interactions are essential for the development of the online examination system.

The series of messages is shown and labeled to guide you in building an online examination system. You can modify the design if you have more ideas. You can also add more features to this design and use it as your project blueprint.

You’ll be able to understand and educate yourself on how the online examination system works by creating a sequence diagram. because it determines the needed objects, actors, and messages and their interactions.

Additional Knowledge on Online Examination System

A computer-based test system that may be used to conduct computer-based tests online is known as an “online examination system.” This test method requires fewer resources and eliminates the need for question papers and answer scripts, as well as exam room scheduling, invigilator coordination, and more.

Alternatively, candidates taking online tests must complete the questions within a set time limit. Once the exam is completed, the test window closes, and institutes receive real-time reports. Evaluators rate the responses based on their evaluation.

Online examination systems can imply savings in both time and money. The saving of time and money spent is also the most significant benefit of doing an online examination. It can improve security and privacy and is environmentally friendly. Both teachers and students will find it very useful.


The online examination system is a sort of interaction sequence diagram that shows how a group of items interacts and in what order. Software engineers and business experts use these diagrams to understand the requirements for a new system or to describe an existing process.

In addition, this online examination system must have a designed diagram to define event sequences that will result in a desired outcome. The context in which communications appear is more important than the message itself. The majority of sequence diagrams, on the other hand, will show what messages are transmitted and in what order they usually occur.

And that completes our discussion, fellas! And I hope that this article about the online examination system will help you a lot.
