"Online Exam System Design and Implementation" is a 17-page document that explores the development and implementation of an online examination system using computer network technology. The document discusses the shift from traditional exam methods to computer-assisted and paperless exams, highlighting the benefits of online exams such as saving resources, improving efficiency and quality, reducing costs, and removing time and space constraints. The main focus of the document is to design a system that allows teachers to break free from traditional paper-based exams and students to break free from traditional learning methods. The exam system consists of front-end web design and back-end question bank system services. The system includes modules for student and administrator information management, exam subject management, question bank management, automatic paper generation, online exams, automatic evaluation, and student performance management. The system is developed using ASP language and integrates question bank management, online exams, and real-time assessment. The document analyzes the key technologies and issues in computerized exam systems and proposes the system structure and software functional modules required for implementation. By improving exam efficiency and feedback, the system aims to make teaching more targeted and learning more effective for both teachers and students. The keywords for this document are: online exam, ASP technology, database development and application, random paper generation. Overall, the "Online Exam System Design and Implementation" document provides a comprehensive overview of the design and implementation of an online exam system using computer network technology.

The database of the system deposites every students' examination time ,questions and points. It displays a online examination system combined with clear interface,safety,conveniency and practicality. The text expatiates a lot of advanced network technology of JSP that used to develop and design the system over basic work flow analysis and analyze of the system function module based on B/S truss of JSP,and the opportunity and predominance to adopt primary technology.It introduces the frondose solving project detailedly.
