校园二手交易系统

摘要I摘要目前，随着计算机网络安全的进一步发展，网上购物已经成为快捷便利的购物手段，电子商务已经融入到现代生活中。因此建立网上购物平台是十分必要的。本文着重阐述了二手物品交易网站的整体开发过程。介绍了系统的开发环境以及开发工具，对于设计思想和设计流程也做出了全面的叙述，在数据库创建思想以及各个数据表之间的具体关联等方面也做出了详细说明，并且具体剖析了系统各个功能的实现过程以及详细设计过程，在绘制简单系统功能模块图的同时，力求更加清晰地表明设计思想以及对整个程序设计的规划及具体实现。并对现行系统存在的问题进行了分析，同时提出二手物品交易网站的设计目标，并从技术、经济、运行三个方面进行了可行性分析。结合现今电子商务平台的现状，对本电子商务网站进行设计，前台开发工具选择微软的VisualStudio.net2005，后台数据库采用SQLServer2000，并综合使用了HTML、C#脚本技术等多种关键技术。另对该系统进行了测试与发布，并选择了适合的推广方法进行推广，最后对此系统进行了评价。本系统最具特色的部分：首先，实现了在线搜索商品的功能，其次，管理员后台功能细致入微，特别是对商品管理的实现，使得本系统更加具有商业价值，适应电子商务类系统的开发需求，为企业提高了工作效率，节省了人力资源。关键词：校园二手交易;网站设计;SQLServer2005;asp.net摘要IIAbstractWiththefurtherdevelopmentacomputernetworksecurity,onlineshoppinghasbecomeanefficientandconvenientmeanstopurchasegoods.E-commercehasbeenintegratedintomodernlife.Thereforebuildingupownon-lineshoppingterraceinHappyFamilyisverynecessary.Thispaperfocusesononlineshoppingsystemasawholedevelopmentprocess.Thesystemdevelopmentenvironmentaswellasdevelopmenttoolsforthedesignandthedesignprocesshasalsomadeacomprehensivenarrative,inthedatabasetocreatedatatables,aswellasthinkingofthespecificlinksbetweensuchareashasalsomadedetaileddescriptionandanalysisofthespecificvariousfunctionalsystems,aswellastherealizationprocessofdetaileddesignprocess,drawingasimplemapofthesystemfunctionalmodulesatthesametime,tomoreclearlythatthedesignofthewholeprocess,aswellastheplanninganddesignofconcreterealization.AndtheexistingsystemoftheproblemsofonlineshoppingAtthesametime,thedesigngoal,andfromthetechnical,economicandoperationalfeasibilityofthethreeaspectsoftheanalysis.Withthestatusofthecurrente-commerceplatform,thee-commercesitedesign,developmenttoolsprospectschooseMicrosoftVisualStudio.net2005,thebackgrounddatabaseusingSQLServer2000,andtheintegrateduseofHTML,C#scriptingtechnology,andotherkeytechnologies.Anotherofthesystemweretestedandreleased,andthepromotionofchoiceofasuitablemethodtopromote,andthefinalevaluationofthissystem.Thesystemmostuniqueparts:Firstofall,theonlinesearchfunctionofthecommodity,andsecondly,administratorbackgroundfunctionnuanced,especiallyfortherealizationofcommoditymanagement,makingthesystemmorecommercialvaluetothedevelopmentofe-commercecategorysystemdemandforenterprisestoimprovetheirworkefficiency,savehumanresources.Keywords:Campussecondarytrading;websitedesign;SQLServer2000andASP.NET摘要III目录引言........................................................................11系统调查与研究...........................................................31.1现行系统调查.........................................................31.2二手物品交易网站的优势...............................................31.3现行系统业务说明.....................................................41.4系统业务流程图.......................................................41.4.1系统流程图的符号..................................................41.4.2系统业务流程图...................................................52可行性分析...............................................................72.1技术可行性...........................................................72.2经济可行性...........................................................82.3用户使用可行性.......................................................82.4法律可行性...........................................................83需求分析.................................................................93.1总体目标.............................................................93.2具体目标.............................................................93.3数据流程图及功能分析................................................103.3.1数据流图基本概念................................................103.3.2系统数据流图.....................................................103.4数据字典............................................................123.4.1数据存储........................................................123.4.2数据流..........................................................143.4.3数据处理........................................................154总体设计................................................................174.1概述................................................................174.2系统功能模块........................................................184.2.1用户模块........................................................184.2.2管理员模块......................................................194.3接口设计............................................................194.3.1外部接口........................................................194.3.2内部接口........................................................204.4数据库设计..........................................................204.4.1概念模型设计...................................................214.4.2数据库物理设计...................................................234.5运行设计............................................................27摘要IV5详细设计................................................................285.1概述................................................................285.2B/S结构实现系统功能.................................................285.3系统程序流程图......................................................295.4系统的界面设计......................................................
