Voting System Use Case Diagram
About the Project
Computer-based voting systems, also known as electronic voting systems, use electronic means to record and tally votes. These systems can take various forms, such as direct recording electronic (DRE) voting machines, which allow voters to directly input their vote into a computer, or internet voting systems, which allow voters to cast their ballot online. Computer-based voting systems have the potential to increase accessibility and convenience for voters, as well as improve the speed and accuracy of vote counting. However, there are also concerns about the security and integrity of electronic voting systems, as they can be vulnerable to hacking and other forms of tampering. To address these concerns, many computer-based voting systems include multiple layers of security, such as encryption and voter-verified paper audit trails, which provide a physical record of the vote that can be used for manual recounts.
In this study, the researchers aim to develop an efficient, accurate and reliable computer-based voting system for the students that could track ballots, speed the counting of ballots and can facilitate electoral fraud. The design of electronic voting system will be based upon the electoral process adopted by the school. The system can be made fully accessible to any computers; information of the student candidates such as their pictures and accomplishments in which the student can identify and determine easily their respective candidate.
What is Use Case Diagram?
A use case diagram is a visual representation of the interactions between users (or actors) and a system, showing the different functions or processes that the system can perform. In the context of a computerized voting system, a use case diagram would show the various actions that voters, election officials, and other actors can perform, such as registering to vote, casting a ballot, and counting votes.
Use case diagrams can be beneficial to the development of a computerized voting system in several ways:
Requirements Gathering: Use case diagrams can help to identify and document the functional requirements of a system, by capturing the different interactions and processes that are needed to support the voting process.
System Design: Use case diagrams can also be used to guide the design of the system, by providing a high-level view of the system’s functional capabilities and the relationships between different components.
Testing and Validation: Use case diagrams can be used to create test scenarios and validate that the system is functioning as intended.
Communication: Use case diagrams can be used to communicate the system’s requirements and design to stakeholders, including voters, election officials, and developers, in a clear and concise way.
Traceability: Use case diagrams can help to maintain traceability between requirements and design, which is essential to ensure that the system meets the needs of the stakeholders and that changes are tracked and managed.
Use Case Diagram
The image above shows the Use Case Diagram of the Voting System. It has three user sides such as the Admin, Student and the Public Viewers. The admin can access the entire core modules of the system. The Student can access the Student Info, Candidates, Voting Module, and Real Time Update modules while the Public Viewers can access the Real Time Update module.

Summary
The main purpose of this capstone project is to develop automated voting software that is user-friendly and reliable. The Electronic Voting System (VOTING SYSTEM) will be developed by the researchers for high school and college level. The proposed project “Electronic Voting System is computer-based software that enables voters to vote smoothly, comfortably, and peacefully during student government elections. The image above shows the Use Case Diagram of the Voting System. It has three user sides such as the Admin, Student and the Public Viewers. The admin can access the entire core modules of the system. The student can access the Student Info, Candidates, Voting Module, and Real Time Update modules while the Public Viewers can access the Real Time Update module.
