具有身份识别的网上投票系统的设计

591论文网具有身份识别的网上投票系统的设计摘要随着网络技术的迅速发展，传统的投票方式已经不能满足人们的需要。而网上投票系统除了能够完成传统的功能之外，更具有时效高和范围广的优点，更符合现代社会的需要。具有动态口令认证机制的网上投票系统的设计是采用ASP和SQLServer2000技术开发的简易投票系统，并在用户登陆过程中设置动态验证码，提高系统的安全性。它实现了以下功能:投票、结果查看、增加、删除及搜索投票等。本论文首先介绍了网上投票系统的概念及和适用范围。在系统开发环境中主要对ASP、SQL和动态口令认证机制的基本概念作了详尽的介绍。接着通过E-R图说明数据库的搭建和数据库的设计。然后介绍了本系统的总体设计，包括：系统结构和总体功能设计。论文以功能模块图的形式说明了功能的设计并给出了部分核心代码及主要功能界面图。关键词：网上投票系统；ASP；SQL；动态验证码591论文网’ssecurity.Itcanbeeffectiveimplementthefunctionofvoting,examining,adding，deletingandsearchingvotes.Tostartwith,thisthesisintroducesthebasicconceptandtheappliancescopeoftheon-linevotesystem.Afterthat,thethesismakedetailedintroductiontothebasicconceptoftheASP,theSQLandthedynamicpasswordauthenticationschemeinthepartofthedevelopmentenvironmentofthesystem.ThenitelucidatesthecreationofthedatabasebytheE-Rdiagramandthedesignofthedatabase.Introducedthetotaldesignofthissystemimmediatelyafter,include:thesystemstructuredesignsandthetotalfunctiondesign.Withtheformofthefunctiondiagram,thesisexplainedthedesignoffunction,showedcorecodeandthesystemcirculateinterfaceofthemainfunction.Keywords:Theon-linevotesystem;ASP;SQL;Thedynamicverifiablecode591论文网目录论文总页数：20页1引言...............................................................................................................................................21.1网上投票系统的概念................................................................................................................21.2网上投票系统概念的提出........................................................................................................21.3网上投票系统的适用范围........................................................................................................21.3.1什么样的主题适合做网上投票.......................................................................................21.3.2网上投票样本的合理性....................................................................................................31.3.3网上投票的程序与方法....................................................................................................32系统体系开发环境.......................................................................................................................32.1系统的硬件环境.........................................................................................................................32.2技术上配合.................................................................................................................................32.3ASP简介.....................................................................................................................................42.4SQL简介.....................................................................................................................................42.5动态口令认证技术....................................................................................................................72.5.1验证码起源.........................................................................................................................72.5.2验证码实现流程................................................................................................................72.5.3网上投票系统中的验证码的作用...................................................................................73数据库的搭建...............................................................................................................................83.1E-R图..........................................................................................................................................83.2数据库的设计.............................................................................................................................93.2.1用户信息.............................................................................................................................93.2.2投票信息............................................................................................................................103.2.3投票选项..............................................................................................错误!未定义书签。3.2.4管理员信息........................................................................................................................114系统详细设计.............................................................................................................................114.1具有动态口令认证机制的网上投票系统的结构.................................................................114.2系统详细功能设计........................................................................
