Online Examination System Class Diagram | UML

ONLINE EXAMINATION SYSTEM CLASS DIAGRAM – is a designed structure that shows the systems’ classes and their relationships. This UML Class Diagram is made to guide programmers along with the Online Examination system development. It contains the systems’ class attributes, methods as well as the relationships between classes. These mentioned contents makes sure that your Online Examination system development is inline with what should be its functions.

Here’s what you need to know about the Class Diagram for Online Examination System. It must contain all the needed information and complete in details. From the Classes, its attributes and methods up to its visibility and relationships, they must be arrange and declared thoroughly. Now you must know what are the needed information before doing your UML Class Diagram for Online Examination System.

Important Considerations before Designing your UML Class Diagram for Online Examination System.

You must be informed that an Online Examination system is a computer-based test system for conducting online computer-based tests. 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.

Here are the advantages once the system is developed:

  • Environmentally responsible.
  • It helps you save money.
  • It saves a lot of time.
  • Technically advanced.
  • Less cheating since the system is more secure.
  • It’s practical.

The goal 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. Therefore you must be aware of all the information needed in constructing its class diagram. The factors mentioned should be present and represented by classes provided with their attributes. You also have to plot their relationships because it will be the guide in the system development.

So if you worry about the UML Class Diagram components, there’s a complete discussion for that. They were given examples and forms for you to fully understand how the diagram works. It discusses the UML Class Diagram Classes, Attributes and Relationships. These are the important factors in building the structure of Online Examination System.

How to Construct Online Examination System UML Class Diagram?

Now to create the Diagram for Online Examination System, you will determine first its classes. So the classes that are included in an Online Examination would be the examinees, examination, exam provider or school, requirements, and subject. The mentioned classes were just general. If you want more complex or wider scope of your Online Examination system, then you can add your desired classes. You must also include the database on your Class Diagram for your system.

After knowing all the necessary classes, you will then assign their attributes and methods in accord to their functions. The attributes and methods’ visibility also matters a lot. You just have to be guided accordingly in creating your UML Class Diagram. This is to keep you from unwanted repetitions and mistakes. And if you have successfully made this diagram, you will then easily build you Online Examination System.

Simple Class Diagram (UML) for Online Examination System

Here, I will be showing you the sample constructed Online Examination System Class Diagram. It was provided with its attributes with matching methods. This is constructed with the simple idea derived from the common function of a Online Examination.

  1. Class Diagram for Online Examination System Construction

    The illustration shown in this article gives you the hint on how will you design your own Online Examination System UML Class Diagram. It has the simple idea on how the class Diagram works.

    It resembles a flowchart in which classes are represented as boxes with three rectangles inside each box. The top rectangle has the class’s name; the middle rectangle contains the class’s properties; and the bottom rectangle contains the class’s methods, commonly known as operations.

    As you can see through the illustration, the classes were determined which is symbolized by boxes. They were designated with their corresponding attributes and shows the class’ methods. Their relationships are also plotted to show the connections between classes and their multiplicity.

    You should also look into the visibility symbols displayed in the diagram. These are important because it declares the status of attributes in your Class Diagram. Some of the Class’ attributes are for public (+) which means that they can be accessed by the classes connected to them. While the protected (#) symbols, means that the attributes of the data can be accessed by the same classes or subclass and the (-) symbol means it cannot be accessed by other class.

    Just bear in mind that when you create your own class diagram, you have to be specific. That is because, it will affect your project development. Do not worry because you can use the sample given as your project reference or you may also create your own.

Bonus Tips on Designing the UML Class Diagram of Online Examination System

To design your Class diagram, you may use platforms and editing tools online. These tools are helpful since they already have the needed symbols to illustrate your class diagram. You just have to plot the included classes, attributes and methods. Then you will put the appropriate relationships that the system requires.

The platforms or online tools that you may use are:


The Online Examination System Class Diagram is a modeled diagram that explain its classes and relationships. The diagram depicts the names and attributes of the classes, as well as their links and, their methods. It is the most essential type of UML diagram which is critical in software development. It is an approach to show the system’s structure in detail, including its properties and operations.

The Online Examination System must have a designed diagram to define the classes needed for the desired outcome. It is used to model the items that make up the system, depict their relationships, and define what those objects perform and the services they provide.

And that completes our discussion fellas! I hope that this article about UML Class Diagram for Online Examination System will help you a lot.
