摘  要
随着计算机技术的发展，越来越多的行业实现了管理的信息化和自动化。教育行业也不例外。为了满足现代教学的需求，进一步加强老师和学生的交流，同时改变过去传统的作业批改方式, 设计了基于B/S 模式的在线作业批改系统。系统包括教师模块和短消息模块，教师模块主要是实现教师布置作业、批改作业、发布成绩等。短信息主要是实现信息的发送、编写、查看。论文详细阐述了系统的开发背景、研究意义，开发环境以及系统的需求分析，详细说明了数据库的设计，以及系统各功能的实现。
在线作业批改系统有着很好的应用前景，用来代替传统的作业批改方式，实现在线作业批改方式的网络化管理。随着计算机技术和网络技术的发展，它的功能将会得到不断的发展和完善。

Abstract
As computer technique develops, more and more trades achieve information retrieva l and automation for management, so as to education. Meeting modern teaching's demands ,online homework correcting system is designed on account of B/S mode, which can improve interchange between students and teachers, changing old traditional ways of homework correcting. The system includes teacher part and messenger part. Teacher part mainly achieves teachers ‘assigning homework, correcting homework and score reporting, while message part mainly achieves message sending, composing and reading. The system’s designing background, studying significance, developing environment and needs analysis are stated with details, so as to data room designing and how parts of the system achieve their function. 
 Online homework correcting system now holds good application prospects, taking place of traditional ways of homework correcting and bring about net management for online homework correcting. As computer and network technique develop, its function will get continual improvement and development.
Keywords: B/S; homework correcting; message; database; .NET
