I摘要随着科技的进步和计算机网络的飞速发展，教育在人们生活中开始占有很重要的地位。为了让人们的学习过程可以不受地域、时间限制，使得教学资源能在最大范围内实现共享，产生了网上教学系统。学习任务的繁重，教师课堂所授知识不能当堂完全理解，教师也不可能一对一的辅导。学生对一个知识点难点持有不同的意见和不同的理解程度，但局限于课堂时间的限制，不能交换意见。一个可以在网上在线学习交流的平台。可以避免传统教学模式下时间和空间的限制；当代学生学习动机呈多样性，学习压力因素各异，而在网络背景下的学习者可根据自身的特点采取不同的学习方法。本在线学习交流平台主要是为在校学习的学生提供一个网络平台，可以让同学无论何时何地，只要有网络的地方就可以进行网上学习，自行安排学习时间，不仅突破了学校授课的地点时间的局限性，更节约了学校的各种资源，而且还节省了老师同学的时间，网上的交流让老师同学更加的自由方便，从学习渠道方面解决学生学习知识。本设计的开发是基于B/S结构，JAVA开发语言，采用MyEclipse开发平台及SQLServer2000数据库进行开发。关键词在线学习交流平台；B/S；JSPIIAbstractWiththeprogressofscienceandtechnologyandtherapiddevelopmentofthecomputernetwork,educationinpeoplelifebegantooccupiesaveryimportantposition.Inordertoletpeople'slearningprocesscannotberegional,timelimit,maketheteachingresourcescanbethebiggestrangesharing,produceanonlineteachingsystem.Workhard,theteachertaughttheclassroomknowledgecan'tcompletelyunderstandtheclassroom,theteachercan'tone-to-onecounselling.Studentstoadifficultknowledgepointshavedifferentideasanddifferentunderstanding,butlimitedtoclasstimelimit,can'texchangeofviews.Astudyintheonlinecommunicationplatform.Toavoidthetraditionalteachingmodeoftimeandspacelimit,Thecontemporarystudents'learningmotivationisdiversity,thepressureofstudydifferentfactors,andinthenetworkunderthebackgroundoflearnersaccordingtotheirowncharacteristicstotakedifferentwaystolearn.Thisonlinelearningplatformismainlyforstudentsstudyinginschoolprovideanetworkplatform,canletstudentsnomatterwhenandwhere,aslongasthereisthenetworkplacecanbeonlinelearning,arrangethelearningtime,notonlybreaktheschoolteachingplacetimelimitations,moresaveavarietyofschoolresources,butalsosavethetimeofmyteachersandclassmates,onlinecommunicationletteacherstudentsmorefreeconvenient,fromlearningchannelstosolvestudents'learningknowledge.ThisdesigndevelopmentisbasedonB/Sstructure,JAVAdevelopmentlanguage,usingMyEclipsedevelopmentplatformandSQLServer2000databasedevelopment.KeywordsOnlinelearningB/SplatformJSPIII目录摘要..........................................................................................................................IAbstract........................................................................................................................II第1章绪论................................................................................................................I1.1课题背景...........................................................................................................11.2目的意义...........................................................................................................11.3国内外研究现状...............................................................................................21.4系统开发环境...................................................................................................2第2章可行性研究.................................................................................................42.1经济可行性.......................................................................................................42.2技术可行性.......................................................................................................42.3操作可行性.......................................................................................................52.4系统业务流程图...............................................................................................52.5本章小结...........................................................................................................6第3章需求分析.....................................................................................................73.1系统的需求分析...............................................................................................73.2系统数据流图...................................................................................................73.3数据字典...........................................................................................................93.4本章小结.........................................................................................................12第4章总体设计.....................................................................................................134.1系统功能图示例.............................................................................................134.2数据库表的设计与实现.................................................................................134.3本章小结.........................................................................................................17第5章网站详细设计...........................................................................................185.1系统运行平台设置.........................................................................................185.2系统功能设计.................................................................................................185.2.1系统登录流程设计..................................................................................205.2.2教师发布作业流程..................................................................................215.3网站主界面设计.............................................................................................21IV5.4后台
