III摘要在互联网飞速发展的今天，仅仅依靠原始的人工收集数据，进行纸质化管理，企业收集信息部门面对大量的信息，在浪费了大量的人力、物力、时间，也无法准确、有效的从中取出关键信息，并做出相应的判断和处理，避免公司的危机和获取发展的机遇。同时，用户也没有一个相对方便、简单上述需求的途径。因此，如何有效收集信息和做出相应的判断和处理是当前急需的。随着科学技术的发展和不断进步，计算机的应用技术也日渐成熟，其强大的功能也深入人心，应用范围早已普及世界各地，并且在各个人们生活和发展的领域占有着必不可少的角色。在拥有先进的计算机技术和成熟的互联网时代下，逐步建立一个完善的、智能的、先进的投票系统。而编写一个在线投票系统，最关键的是可以根据用户的需求，快速、简单的创建一个投票的主题，设定投票的时间段，并实现从数据库中添加被选对象，发布到前台。也可对过期或错误的活动进行修改和删除，还能及时查看投票的进程和反馈的结果，满足用户的实时性查询。在登陆系统时，对用户的身份进行判定，每个账号都有不同的权限。普通账号只能对活动没有过期的活动进行投票和查看结果，而管理员账号不但可以进行投票和查看结果，而且还可以在后台对过期用户和活动进行处理。本次毕业设计的内容是设计并且实现一个基于Java-web的在线投票系统，系统将使用Eclipse来作为开发工具，而数据库则使用的是中小型数据库--MYSQL，以及用到了Dreamweaver作为界面开发工具。本次项目基本实现了网上在线投票系统应有的主要功能模块。关键词：在线投票系统JAVAMYSQLAbstractIVAbstractToday,therapiddevelopmentoftheInternet,relyingonlyontheoriginalmanualcollectionofdatatocarryoutpapermanagement,enterprisecollectioninformationdepartmentfacealargeamountofinformation,wastealotofmanpower,materialresources,time,andcannotaccuratelyandeffectivelyremovethekeyinformation,andmakethecorrespondingjudgmentandtreatmenttoavoidpublic.Thecrisisofthedivisionandtheopportunitytogaindevelopment.Atthesametime,usersdonothavearelativelyconvenientandsimplewaytomeettheaboveneeds.Therefore,howtoeffectivelycollectinformationandmakecorrespondingjudgmentsandtreatmentsisurgentlyneeded.Withthedevelopmentandcontinuousprogressofscienceandtechnology,theapplicationofcomputertechnologyisalsomature,itspowerfulfunctionisalsodeeplyrootedinthepeople'smind.Theapplicationscopehaslongbeenpopularizedallovertheworld,anditoccupiesanindispensableroleinthelifeanddevelopmentofthepeople.WithadvancedcomputertechnologyandmatureInternetera,wewillgraduallyestablishaperfect,intelligentandadvancedvotingsystem.Towriteanonlinevotingsystem,thekeyistocreateavotingtopicquicklyandsimplyaccordingtotheneedsoftheuser,setthetimeofthevote,andaddtheselectedobjectsfromthedatabaseandpublishittothefrontdesk.Itcanalsomodifyanddeletetheoverdueorerroneousactivities,andcanalsochecktheprocessofvotingandtheresultoffeedbackintimetosatisfytheuser'sandmeettheuser'sreal-timequery.Inlandingsystem,theuser'sidentityisdetermined,eachaccounthasdifferentpermissions.Ordinaryaccountscanonlyvoteandviewtheresultsofactivitiesthathavenotbeenoverdue,andtheadministrator'saccountcannotonlyvoteandviewtheresults,butalsohandletheoutdatedusersandactivitiesinthebackground.ThecontentofthisgraduationdesignistodesignandimplementanonlinevotingsystembasedonJava-web.ThesystemwilluseEclipseasadevelopment
