The Online Exam Management System Design and Development is an innovative practice that combines modern information technology with the education sector. With the rapid development of network technology and remote education, such systems have become a focal point in the field of education. This article delves into the theory, technical background, system design methods, and implementation process of the online exam management system. Before system design, a thorough study of the current status of online exam management is necessary to evaluate its feasibility and necessity. This involves a needs analysis of educational institutions, including exam organization, question bank management, student management, grade statistics, etc. Through these analyses, the main goals of the system can be clarified, such as improving exam efficiency, reducing human errors, enhancing user experience, and ensuring fairness and security. In the system design phase, it is crucial to determine the operating model and architecture. The B/S (Browser/Server) architecture is adopted, allowing users to access the system through a web browser, which reduces client-side maintenance costs while enhancing the system's accessibility and cross-platform compatibility. A modular design method facilitates system scalability and maintenance by dividing system functions into independent modules, such as user management, question bank management, exam module, and grade management. During the implementation process, VP-UML is used as a modeling tool to create system requirement models, use case models, class models, and sequence diagrams, helping designers clearly express the system's design ideas. ASP.NET, as the development language, is an object-oriented, extensible programming technology based on the .NET Framework, capable of quickly building dynamic web applications. SQL Server 2005 serves as the backend database, providing data storage and management functionalities, supporting complex queries and transaction processing to ensure data security and consistency. The core functions of the online exam system include user registration and login, automatic paper generation, manual paper generation, online exam, auto-grading, and grade management. The user registration and login module ensures that only authorized users can participate in the exams. The automatic and manual paper generation functions can generate exams based on preset rules or teacher selections. The online exam module allows students to complete the electronic exam within a specified time and submit their answers in real time. The auto-grading feature quickly calculates grades based on set scoring rules. The grade management module stores, counts, and displays student exam results. In practical application, the system must also consider security and stability, such as preventing cheating, ensuring stable network connections, and implementing data backup and recovery mechanisms. Moreover, the system should offer a user-friendly interface and experience for easy operation. In conclusion, the online exam management information system, by combining advanced information technology, realizes the digitization and networking of exams, improving the efficiency and quality of exam management. Through proper design and implementation, it can meet the diverse needs of educational institutions in a remote education environment and promote the modernization of education.
