粮食市场竞价交易电子

1粮食市场竞价交易电子商务系统开发摘要进入21世纪，电子商务凭借互联网的支持迅速发展并逐渐成熟。其中，网上竞价交易已经成为农业电子商务的重要组成部分，也是近年来研究的热点。随着电子商务的快速发展，传统的Web应用开发技术暴露出许多不足之处，造成了Web应用开发的效率降低、成本上升、扩充与维护困难、分工合作不好进行等问题，限制了互联网的发展。针对以上不足之处寻求解决方案，建立一个功能完善的网上竞价交易系统。本课题的主要目的是为粮食交易双方搭建了一个灵活自由并且安全可靠的交易平台。粮食市场竞价交易电子商务系统是农产品在线竞价交易系统，用信息发布和配送等采用电子化手段取代传统方式，通过网络及时将粮食信息反映给政府管理部门，在突发事件来临时起到预警作用。网上竞价交易是新兴起的一种网上交易方式。它具有成本低廉，方式灵活，运行快捷等特点。随着技术的进步和市场竞争的加剧，粮食交易市场的运作愈来愈依赖于采用计算机互联网技术、数据库技术、网络安全技术等现代信息技术组建的为粮食竞价交易活动提供服务的信息平台――粮食市场网上竞价交易系统。结合目前软件工程、WEB技术、数据库等先进技术，应用MicrosoftVisio进行软件建模。以.NET为开发平台，用VisualStudio.NET开发环境，利用Microsoft公司提供的ASP.NET、C#编程语言、SQLSERVER2000数据库实现农产品在线展示、会员自助注册，供应商发布竞价信息，竞价购买、一口价购买、购物车的实现、留言板以及订单管理等功能。把所有模块在.NET中将系统进行整合，最后经过性能和功能测试成功后，完成整个粮食竞价交易电子商务系统的设计与开发。关键词：电子商务；竞价交易系统；粮食交易2AbstractAfterenteringthe21stcentury,E-commercedeveloprapidlyandmaturitybyvirtueoftheInternet.TheonlineauctionbecomesanimportantcomponentofE-commercetransactions,whichisalsotheresearchhotspotinrecentyears.WithE-commerceapplicationsdevelopingrapidly,thetraditionalWebapplicationsdevelopmenttechnologyhaveexposedmanyinadequacies,whichresultinefficientreducing,costincreasing,andtheexpansionandmaintenancedifficulties,nottocarryoutsuchissuesasdivisionoflaborofWebapplicationdevelopmentalsolimitingthedevelopmentoftheInternet.Owingtotheinadequaciesoftheaboveweneedtofindasolutiontobuildafullyfunctionalforonlineauctiontradingsystem.Themainpurposeofthesubjectistosetupafree,safe,reliableandflexibletradingplatformforthebothsidesofthefoodtrade.ThegrainmarkettradingE-commercesystemisforagriculturalproductsauctiontradingsystems.Itcanpublishthenewinformationofgrainauctiontradingbymeansofelectronictoreplacethetraditionalway;canalsoreflectthefoodinformationtothegovernmentadministrationsectionthroughthenetworkintime,whichwillplayaroleoftheearlywarningbeforesomeunexpectedeventshappen.Onlineauctiontransactionistheemergenceofanewwayofagricultureonlinetransactions.Itislow-cost,flexibleandquicktorunandsoon.Withthedevelopmentoftechnologyandmarketcompetition,theoperationofthefoodmarketismoreandmoredependentontheuseofInternettechnology,databasetechnology,networksecuritytechnologies,suchastheformationofmoderninformationtechnologyforthefoodauctiontradingplatformtoprovideservices--Thegrainmarketonlineauctiontradingsystem.Withthecurrentsoftwareengineering,WEBtechnology,databases,andotherfieldsofadvancedtechnology,MicrosoftVisioapplicationsoftwaremodeling,usingthe.NETplatformforthedevelopment,underVisualStudio.NETdevelopmentenvironment,usetheMicrosoftCorporationtoprovideASP.NET,C#programminglanguage,SQLSERVER2000databasetoachieveprimaryproductsdisplay,onlinesales,aregisteredmemberself-service,biddingmanagementmodule,theshoppingcart,newsandmessageboard,ordersmanagementandotherfunctions.AllthemodulesinASP.NETsystemwillbeintegrated,afterthefinalperformanceandfunctionaltestissuccessful,thecompletionoftheentiree-commercesystemsdesignanddevelopment.Keywords:E-commerce;AuctionTradingSystem;GrainTrading贵阳学院课程设计1目录第1章前言.........................................................................................................................31.1课题的研究背景及现状.........................................................................................31.2课题的提出及意义...............................................................................................41.2.1课题的提出.................................................................................................41.2.2课题的意义.................................................................................................41.3课题的研究内容及重点.......................................................................................51.4系统的研究思路与方法.......................................................................................6第2章课题相关业务与技术介绍...................................................................................82.1业务介绍...............................................................................................................82.1.1电子商务的简介及发展.............................................................................82.1.2网上竞价交易简介.....................................................................................82.2技术知识...............................................................................................................92.2.1应用框架的开发思想.................................................................................92.2.2ASP.NET技术...........................................................................................9第3章系统分析.............................................................................................................123.1系统需求分析.......................................................................................................123.2识别角色与用例.................................................................................................123.2.1识别角色与用例.........................................................................................123.2.2系统用户活动图分析..................................................................................153.3系统总体规划及功能需求......................
