The online examination system use case diagram is the behavioral diagram that summarizes activities done in the online examination system and its user details. It depicts the graphical representation of the system’s behavioral structure.
Additionally, the diagram consists of processes (use cases) and users or “actors”. It uses defined symbols to describe the overall workflow of the online examination system.

What is a Use Case Diagram?
The use case diagram in software engineering shows the sample adaptive behavior of the online examination system. It encapsulates the project’s functionality by incorporating use cases, actors, and their interactions.
Moreover, the diagram assists you in defining and organizing project requirements. This also provides a clear picture of the user and system relationships. Therefore, this diagram depicts the high-level functionality of a system including how the user interacts with it.
Importance of UML Use Case Diagram
To help the developers and enterprises in developing the system is the importance of the UML use case diagram. It includes the procedures from the viewpoint of users.
Furthermore, the diagram is the analysis methodology used to identify, clarify, and organize project needs. This diagram works best with other UML Diagrams for Online Examination System. Other UML diagrams include activity, class, sequence, deployment, and component diagrams.
Online Examination Management System Use Case Diagram
General Use Case Diagram
The general use case diagram for online examination management system shows the general processes or functions of the system. This is based on the transactions needed in doing or conducting Online Examinations.
Use Case Diagram using Include and Extend
The include and extend are used to elaborate the proceeding diagrams. The terms include and extend in the use case diagram are known as indicators.
The broken arrows are indications that the following diagrams connected to them are parts of a process. They could either be one of the indications which were the include or extend.
The “include” indication means that the following use case was compulsory to finish the task and the “extend” indication is otherwise.
The role of this diagram using include and extend is to inform your readers and users that some tasks and processes may be completed without invoking all the subtasks. They were only used when they were called or needed.
You can add more to this deigned diagram and it is up to you how will you create your diagram. But make sure to have precise information and consider the included use cases.

How to draw a Use Case Diagram?
Time needed: 2 minutes
Here’s the complete guide on how to draw a use case diagram for online examination system.
- Step 1: Familiarize Use Case Diagram Symbols
For beginners in the field of designing the diagram, you need first to familiarize the symbols to be used.
- Step 2: Determine the targeted users
The next step is to determine your targeted users. They will be the ones to use your project.
You may ask the users about the typical activities done in online examinations.
- Step 3: Analyze the use cases included
The gathered information from the users needs to be evaluated to know the general use cases.
From the general use cases, you will see the sub-cases that are included. But, only the useful processes and circumstances related to the online examination system.
- Step 4: Plot the Use Case Diagram
To plot the diagram you will need the users, use cases, container (scope), and their indicators (association). You will base the flow of use cases on the evaluated information from the users.
You need to place first the users involved.
Then place the figured use cases included in doing the process.
After that, you will trace the association of the use cases to know the interactions between the user/s and the system.
Finally, put the container in the plotted diagram to separate the objects’ (users and system) scope.
The use case diagram is one of the methods that contribute to the online examination system design and development. It helps developers know the possible inputs and scenarios that the project should process and perform.
Furthermore, you will find out the needed processes and connect them to the other UML Diagrams. The diagram is also applicable in modeling the software’s use cases (processes). It also captures the system’s flow from one process to the next.
