摘 要

随着网络高速地融入当今现代人的生活，学校对网络技术的应用也在不断地提高。学校的教学任务十分复杂,工作也很繁琐,在教学任务中，作业的批改也是一个很重要的环节。为了提高老师工作效率，减轻教师的工作强度，提高作业批改的灵活性，《通用作业批改系统》的诞生可以说是事在必行的。该系统采用B/S结构，以浏览器方式登陆系统，用ASP.NET作为开发语言，数据库则使用Microsoft SQL Server 2000实现。《通用作业批改系统》包括了学生子系统、教师子系统、管理员子系统三大模块，该系统主要完成学生，教师，管理员的登陆，作业的提交，批改等功能，具有操作简单、界面友善、灵活性好、系统安全性高、运行稳定等特点。

本文简要介绍了《通用作业批改系统》的项目背景和意义，着重阐述了该系统的设计实现过程与该系统数据库的设计实现过程；从系统的需求分析、模块设计、数据库设计到系统实现等各个环节都进行了详尽的分析和描述。

General Homework Correct System

Abstract

With the high-speed network melting into modern life, the application of network technology at school also increases continually. The teaching mission of the school is very complicated, and work is also very tedious, it is obvious, the homework correct is also a very important link in the teaching mission. For raising teacher's work efficiency and the agility of homework correct, easing the teacher's work strength, the birth of <> can be said to be in inevitable. The system uses B / S structure to Browser landing system, using ASP.NET as a development language, database using Microsoft SQL Server 2000 to achieve. <>includes a subsystem of students, teachers subsystems, and the three major subsystems administrator module, The system accomplished the loading of students, teachers and managers, handing over the homework, and correcting. The system contains many strong points such as simply operation, friendly interface, high agility and system safety stable circulates.

This paper introduced the item background and meanings of <

Correct System >>in brief , and elaborates the design and realization courses of the system and the database of the system .And it describes every links from the needs analysis ,module design ,database design to system realization.

Key Words：Upload operations; Correction；System Realization
