学号密级哈尔滨铁道职业技术学院毕业论文WEB作业系统学院名称：计算机学院专业名称：计算机网络学生姓名：林鹏指导教师：张雪讲师二○一一年六月2摘要随着计算机网络的迅速发展，当前，国内外的教学的模式由传统的教学模式逐步向网络教学模式迈进。基于Web的现代教育是一种新型的教育方式，越来越受到人们的关注并逐步取代传统教育，21世纪它将成为构筑终身学习体系的主要手段。而基于Web的作业管理系统系统则是实现现代网络教育的一个重要组成部分，在整个教学过程和教学结果中扮演着尤为重要的角色。一个完善、健全的在线作业系统能及时、准确地反馈教学结果，为教学提供更有意义的指导性策略，优化整个教学过程。在进行网络教学时，还普遍存在着采用FTP或是设置文件夹共享让学生上交作业的做法，这存在多方面的缺点：第一，由于上传的所有作业学生都能够访问，因此，可能会出现学生之间相互抄袭作业的情况；第二，学生不按规定上传作业，如作业的名称，上传路径等；如果是设置共享上传作业，还会出现恶意删除其他同学作业的情况。第三，教师对作业管理困难。针对此种情况，开发一个基于Web的作业管理系统，教师可在网上进行作业的发布，同时对学生的作业进行评分；学生必须注册一个合法帐户才能登录本系统，在线提交作业，查看和修改自己的作业，上次作业未完成还可下载后继续完成，并可查询自己每次作业的成绩。关键词：Web作业系统，ASP，B/SiiAbstractWithcomputernetworkstotherapiddevelopmentofthecurrent,andtheteachingoftraditionalmodeofteachingofthenetworkgraduallytomoveforward.basedonthewebofmoderneducationisanewtypeofeducation,growingattentionandgraduallyreplacethetraditionaleducation,The21stcenturywillbeconstructedofthesystemoflife-longlearning.butbasedonthewebofoperationsmanagementsystemisamodernsystemofnetworkforeducationasanimportantpartintheteachingprocessandteachingresultswereparticularlyimportantroletoplay.Acompleteandimprovethesystemisonlinehomeworkintime,accurateinformationteachingresults,toteachingprovidemoremeaningfulguidingpolicy,andoptimizetheteachingprocess.Onthenetworkteaching,therewaswidespreaduseftporsettingsfilesharingtomakestudentshandedinhishomework,theexistenceofmanyfaults：First,fortheworkofallstudentsareabletoaccess,therefore,mightoccurbetweenstudents抄袭homework；second,thesituationisnotrequiredhomeworkassignments,suchasyournameandpathfor；ifitisasharedthework,tocometoharmtherestofthesituation.third,theadministrationtoworkhard.Inthecircumstances,developingawebbasedontheoperationsmanagementsystemandteachersbutontheinternetforthejobofpublishing,forstudentsingrade；Studentsmustregisteralegalaccountcanloginoursystem,theonlinesubmitassignments,viewandmodifyherownhomeworkanddidn'tfinishtheworkcanalsodownloadcontinuetobecompletedandforeachofhishomework.Keywords：system,aspwebhomework,andb'siii目录1绪论.........................................................................................................................11.1研究背景.......................................................................................................11.2问题与发展状况...........................................................................................11.3Web作业系统研究的启示与建议...............................................................11.4本文工作.......................................................................................................22相关技术概述.........................................................................................................42.1系统构架.......................................................................................................42.2ASP技术.......................................................................................................52.3SQLServer2000数据库概述......................................................................73系统设计.................................................................................................................83.1系统需求分析...............................................................................................83.2系统实现目标...............................................................................................83.3系统的主要工作流程...................................................................................93.4系统模块功能设计.....................................................................................113.5数据库设计.................................................................................................153.5.1数据流程图与数据字典...................................................................153.5.2数据库概念设计...............................................................................173.5.3数据库逻辑结构设计.......................................................................174系统实现...............................................................................................................214.1系统运行环境.............................................................................................214.2数据库的连接.............................................................................................214.3学生自由空间.............................................................................................214.3.1文件上传的实现...............................................................................214.3.2密码修改的实现...............................................................................244.3.3文件下载...........................................................................................254.4作业和考试系统的实现.............................................................................264.4.1上传作业文件的实现.......................................................................264.4.2信息完善的实现...............................................................................29iv总结.............................................................................................................................31参考文献....................................
