在线作业管理系统毕业论文

I基于J2EE的在线作业管理系统摘要:随着信息技术的迅速发展，多媒体计算机、网络为代表的信息技术给教育的发展带来了新的生机，为传统的教学方式注入了活力，给其带来了重大的革命。网络使教育传播不再受时间和地点的限制，开发和充分利用网络教学，是当前教育发展的必然趋势。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。本系统在架构上采用了当前流行的B/S结构，通过JSP、Struts2、Mysql数据库等软件的强大功能完成了作业管理系统教师及学生角色的基本作业管理功能，还具备了一个特别的定时发布作业功能，使教师可以预先设置将要发布的作业，解决了教师出差或忙碌时无法准时发布作业的问题。关键词：作业管理,Java,JSP,Struts2,MySqlIIHomeworkmanagementsystemAbstract:TherapiddevelopmentofIT，therepresentitivesofwhicharenetworkandcomputers,hasbroughtlifeandenergytotraditionalwayofeducation,evokingthehistoricalrevolution.Educationalcommunicationisfreeofthelimitationoftimeandsitebecauseofnetwork.Tomakefuluseofonlinelearningisthetrendofdevelopmentofeducation.Asthecorepartofnetworkteachingsystem,theonlinehomeworkmanagementsystemplaysanimportantpartinenhancingtheefficiencyandqualityofmanagent,Tomakeuseoftheadvantageofnetwork,itcanmeetthedemandoffastspreadingofhomeworkinformationandextendthefunctionofhomework,increasingthevalueofhomeworkinteachingpratice.ThissystemusestheprevailingstrutureB/S,takingtheadvatageofjsp,struts2andmysql,torealizethebasicfunctionofteacherandstudentinhomeworkmanagementsystem.whatismore,italsohasthespecialtimingpublishinghomeworkfuntiontohelptheteacherswhocannotdothatontime.Keywords:homeworkmanagementsystem,Java,Jsp,Struts2,MySqlIII目录摘要...................................................................IAbstract:...............................................................II第一章绪论...................................................................................................................................11.1研究的背景........................................................................................................................11.2研究的内容........................................................................................................................11.3研究的意义........................................................................................................................2第二章系统的设计模式与技术准备...........................................................................................32.1系统的设计模式................................................................................................................32.2技术准备............................................................................................................................3第三章系统分析...........................................................................................................................93.1可行性分析.........................................................................................................................93.1.1经济可行性分析.....................................................................................................93.1.2技术可行性分析...................................................................................................93.2需求分析.............................................................................................................................93.2.1系统运行环境........................................................................................................93.2.2系统功能需求........................................................................................................93.2.3系统性能需求......................................................................................................123.2.4主要功能要求......................................................................................................13第四章系统设计.........................................................................................................................144.1系统业务流程分析..........................................................................................................144.2功能模块的分析与设计..................................................................................................14第五章数据库设计.....................................................................................................................165.1数据库需求分析...............................................................................................................165.2数据的组织与存储...........................................................................................................165.3逻辑设计..........................................................................................................................17第六章系统实现.........................................................................................................................206.1系统研发原则..................................................................................................................206.2系统的实现......................................................................................................................21第七章结论.................................................................................................................................367.1工作总结与成果..............................................................................................................367.2不足及尚待解决的问题.........
