基于.NEt网上论坛系统的设计与实现

本科毕业设计（论文）基于.NEt网上论坛系统的设计与实现学院计算机学院专业网络工程（网络系统开发与管理方向）年级班别2006级（1）班学号3106007104学生姓名赖柯明指导教师蒋艳荣2010年6月I摘要随着计算机技术的飞速发展，特别是近年来互联网的应用与普,人们在网上的交流越来越频繁，这为网上论坛的发展提供了机遇。论坛即BBS，意思是电子公告板，是一种在Internet上常见的用于信息服务的WEB系统，它主要给浏览者提供一个相互沟通和交流的平台。为了方便系统的管理和维护，该系统被设计成前台和后台两个模块。前台系统给用户提供了一个方便自由的交流平台，包括浏览帖子、发布帖子、回复帖子和搜索帖子等。论坛的后台系统为管理者提供了一个方便快捷的在线管理功能，包括板块管理、版主任免、用户管理和帖子管理等。通过对帖子和用户进行有效的管理，为论坛创造一个和谐、温馨的交流环境。首先，本系统采用当前流行的B/S结构，其具有交互便捷、共享性强和信息采集灵活等特点。本文概述了系统开发过程中所涉及的相关技术，包括采用的开发架构、开发工具和开发语言等。其次，本文详细介绍了系统的设计，包括可行性分析、系统需求分析和系统概要设计。最后，本文详述了系统的实现，包括数据库的设计和实现、系统主界面和后台管理功能等的实现。关键词：论坛，BBS，B/S结构IIAbstractWiththerapiddevelopmentofcomputertechnology,especiallytheapplicationandpopularizationoftheInternetinrecentyears.Peopletointeractonlinemorefrequently,thisonlineforumforthedevelopmentofopportunities.ForumthatBBS,whichmeansthatelectronicbulletinboard,isacommonintheInternetontheWEBforinformationservicessystem,itismainlyforvisitorstoprovideaplatformformutualcommunicationandexchange.Tofacilitatethemanagementandmaintenanceofthesystem,thesystemisdesignedtobothfrontandbackofficemodules.Frontsystemprovidesusersaconvenientplatformforfree,includingbrowsingmessages,postmessages,replytootherpostsandsearchmessages.Forumsystemmanagementofbackgroundprovidesaconvenientandefficientonlinemanagementfunctions,includingblockmanagement,Moderatordismissal,usermanagementandmessagemanagement.Postsandusersthrougheffectivemanagementoftheforumtocreateaharmoniousandwarmenvironmenttocommunicate.First,thesystemusesthepopularB/Sstructure,interactiveandconvenient,strong,andinformationsharinggatheringflexible.Thispapersummarizesthesystemdevelopmentprocessinvolvedinrelatedtechnologies,includingthedevelopmentofarchitecture,developmenttoolsanddevelopmentlanguages.Second,thepaperdescribesthesystemdesign,includingfeasibilityanalysis,systemrequirementsanalysisandsystemleveldesign.Finally,detailsofthesystemimplementation,includingdatabasedesignandimplementation,thesystemmaininterfaceandbackofficemanagementfunctionsrealized.Keywords:Forum,BBS,B/SstructureIII目录1绪论.................................................................11.1课题的背景、来源及研究意义......................................11.2研究目的和研究内容..............................................11.3研究领域的现状..................................................21.4研究方法........................................................31.5论文结构........................................................32相关技术介绍..........................................................42.1ASP.net.........................................................42.2C#语言.........................................................62.3SQLServer2005..................................................72.4SQL语言.......................................................83系统可行性研究........................................................93.1技术可行性分析..................................................93.2经济可行性分析..................................................93.3操作可行性分析..................................................93.4法律可行性分析..................................................94系统需求分析.........................................................115系统概要设计.........................................................125.1设计目标.......................................................125.2开发运行环境...................................................125.2.1系统开发架构..............................................125.2.2系统运行架构..............................................135.3系统设计模式...................................................135.4功能模块划分...................................................145.4.1系统总结构图..............................................145.4.2各模块功能和权限描述......................................155.4.3系统总流程图..............................................176系统数据库设计和实现.................................................186.1数据库选择.....................................................186.2各模块E-R图...................................................186.3系统总体E-R图.................................................21IV6.4数据字典.......................................................227系统关键模块的设计和实现.............................................267.1论坛包含的项目文件.............................................267.2论坛前台主要功能模块设计.......................................267.2.1网站前台系统概述..........................................267.2.2论坛首页设计..............................................277.2.3子版块帖子显示页面设计....................................317.2.4系统注册和登录页面........................................327.2.5用户个人中心页面..........................................347.2.6帖子详细信息显示和回帖页面................................347.3网站后台主要功能模块设计.......................................357.3.1板块集管理................................................367.3.2普通板块管理..............................................387.3.3用户管理..................................................407.3.4帖子管理..................................................40结论..................................................................42参考文献.............................................................43致谢....................................
