Online Examination System Use Case Diagram
The capstone project, “Online Examination System,” is a platform for taking college entrance exams. The proposed solution is a computer-assisted examination. The entrance examination will be web-based, and the staff in charge will no longer prepare a large number of examination papers. Students will also not need to bring anything with them, such as pens. They will only use the system to take the entrance exam.
An online examination system use case diagram is a visual representation of the interactions between the system and the users of the system. It is used to model the functionality of the system and to identify the users and their needs.
The use case diagram should be divided into four main sections: the system, the users, the data, and the processing. The system section includes all of the components of the online examination system, such as the server software, the database, and the user interface. The users section includes all of the people who will use the online examination system, such as students taking exams, professors grading exams, and administrators managing the system. The data section includes all of the information that is used by the online examination system, such as questions and answers for exams, course material for professors, and student records. The processing section includes all of the functions that are performed by the online examination system, such as displaying questions and answers on a screen, grading exams, and sending notifications to users.

Table of Contents
The various use cases that a system can handle and the various actors that can interact with the system can both be shown using a use case diagram. Use case diagrams can be used to represent the various ways a system’s functionality and user interface can be represented. Use case diagrams are a useful tool for documenting the various applications of a system and for comprehending how various actors use the system.
Online Examination System Use Case Diagram
The admin of the system can access the entire core modules of the system except the take exam modules while the customer can access exam schedule, exam result, and take exam modules.
Purpose of Use Case Diagram
The purpose of a use case diagram is to capture the functional requirements of a system. A use case diagram captures the user’s interaction with the system, and the resulting actions or results that they achieve. Use case diagrams can be used to illustrate how a system works, and to identify any potential problems that might exist with its functionality.
A use case diagram is also an effective tool for documenting the domain knowledge of a system’s users. By depicting how users interact with the system, use case diagrams can help developers and designers understand the requirements of a domain. Additionally, use case diagrams can be used to identify potential problems with a system’s functionality before they occur.
Finally, use case diagrams can be used to simplify the design process by documenting the interactions between different parts of a system. By understanding the requirements of a domain, developers can more easily create code that meets those requirements. Additionally, use case diagrams can help designers understand how users will interact with a system and which features are required for them to be successful.
