Design And Implementation Of Distance Education Online Examination System Based On J2EE

With the rapid development of network technology, the examination methods have undergone tremendous changes, network-based examination system has become one of the current hot research. Online examination system fundamentally resolves issues such as heavy workload, low efficiency, long feedback cycle, waste of resources and so on. It greatly improves the efficiency of the examination and breaks through the limitations of time and space for examination and educational administration so that it can save a lot of manpower, material and financial resources. Online examination system will be the trend of modern educational technology development and research.The study of Online Examination System focuses on the practicality and feasibility. Distance education based on network technology is a new way of teaching, this teaching method breaks through the traditional mode of education, education delivery can be implemented across time to space through this method. Online examination system is an important part of distance education, Online examination system fundamentally resolves issues such as heavy workload, low efficiency, long feedback cycle, waste of resources and so on. It greatly improves the efficiency of the examination and breaks through the limitations of time and space for examination and educational administration so that it can save a lot of manpower, material and financial resources. Online examination system will be the trend of modern educational technology development and research.Online Examination System study focuses on the practicality and feasibility. Online examination system was designed and implementated according to the actual needs and teaching conditions, it will maximize the benefits of paperless examination after put into use. The advantages and problems of existing online examination systems was analyzed, a clear functional requirements and non-functional requirements of the system was determined, functional structure and database structure of the system were designed, the specific implementation of the system under network environment was researched in this paper. Finally, the function and performance of the system has been tested to ensure that the system reaches the user's expectations.This system uses Myeclipse as the main development tool, uses J2EE technology to build the front page and uses SQL Server 2008 database as a background support, ultimately realizes functions such as student registration, information modification, online examination, exam scores and curriculum management, view student information and grades.
