摘 要

随着社会的进步，网络技术的发展为教育界提供了一片崭新的空间，传统的教学已无法满足学校，老师以及学生的需求。新的教学模式——在线教学系统已逐渐融入广大的教师以及学子中。在线教学已经成为培养人才，促进科研和教育事业发展的重要途径。

作业作为一项重要的教学活动，解决作业的方便提交、发布等问题是教学顺利有效进行重要条件。因此基于Web的作业管理系统便成为网络教学系统不可或缺的组成部分借助计算机及网络的优势，它能实现作业信息的快速传递，并扩展作业的功能，提高作业的教学价值及管理效率及质量。

针对以上问题，设计开发了网上作业批改系统，本系统前台主要使用JSP作为开发语言，后台使用SqlServer作为数据库管理系统，开发环境是MyEclipse，服务器采用tomcat，开发出的一个基于Web技术的B/S结构的基于在线布置作业、在线提交、批阅一体的管理系统。

关键词：作业管理，WEB，JSP，B/S结构

ABSTRACT

With the progress of society, the development of network technology for the education sector to provide a new space, the traditional teaching has been unable to meet the needs of the school, teachers and students. The new teaching mode -- online teaching system has been gradually integrated into the majority of teachers and students in. Online teaching has become a personnel training, scientific research and education development important way.

As an important teaching activities, homework submission, convenient release problem is smooth effective teaching are important condition. Therefore, based on the Web operating management system will become the network teaching system is an indispensable part of the computer and network advantages, it can realize the operation quick transmission of information, and expand the operation functions, improve the operation and management efficiency and quality of teaching value.

In view of the above problems, design and development of online job correcting system, this system mainly uses the JSP as a development language, the use of SqlServer as a database management system, the development environment is MyEclipse, server using tomcat, developed a Web technology based on B / S structure based on online homework, online submission, marking one of the management system.

Key words: job management, WEB, JSP, B / S structure
