基于 ASP.NET+SQL 的通用作业批改系统
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 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 <<General
Homework Correct System >> 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. <<General Homework Correct System
>>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 <<General Homework
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

引 言
在国内，从学生作业管理系统的管理情况来看，在现代化教育技术模式下，使
用计算机提交作业已相当普及。但能够合理使用硬件资源，有条理地管理好学生作
业信息的却少之又少。
通过网络的了解，已经有不少高等学校已经推出了自己的作业上传系统[1]。但
是由于实现技术有限，系统的功能不完善，而且存在很多缺陷。例如：查询不全
面、容易导致系统不稳定，数据库缺乏管理，数据缺乏更新，而且容易丢失。由于
这些缺点造成用户对系统不信任，于是又回到传统的“拷贝、粘贴”方式。系统就
荒废了。
本文阐述了如何运用 ASP.NET 技术[2]构建一个网上作业提交和批改系统的过程，
描述了 B/S 模式的概念及特点，ASP.NET 的优越性及对通用作业批改系统的分析，该
系统主要完成了作业的上传，教师对作业的批改，系统得稳定性高，操作简单。
