本科毕业设计题目：基于ASP+SQL的二手书信息管理系统的设计与实现二手书交易系统摘要：“二手书网上交易系统”打破了传统的销售形式，将书店和网络结合是一种典型的购物网站运用。“二手书交易系统”实际上是运行在Web服务器中的一个Web应用程序。利用页面、脚本程序来实现二手书的销售，展示，求购和供货等操作，本系统是符合时间意义的，在我国每年都有大量的大学生毕业，可是他们用的一些图书就不在进行阅读，为了能够让下一届学生更好的应用我们开发了本系统本文以实际运用为开发背景，运用软件工程原理和开发方法，采用ASP.Net技术构建一个基于B/S模式的二手书交易系统。整个开发过程首先对系统进行需求分析，得出系统主要功能，数据流图及数据字典。接着对系统进行总体设计和详细设计。总体设计主要包括系统功能设计，系统总体结构设计，系统数据结构设计和系统安全设计等；详细设计主要包括系统数据库访问的实现，主要功能模块的设计与具体实现，模块实现关键代码等[1]。最后对系统进行了功能测试，并对测试结果进行了分析总结，得出系统的不足及需要改进的地方，为以后的系统维护提供了方便，同时也为今后开发类似系统提供了借鉴和帮助。本系统的开发使二手书交易管理更加方便快捷，同时也促使二手书交易系统的更加系统化、有序化。系统界面较友好，易于操作。关键词：二手书，销售；ASP.Net技术；B/SSecond-handBookTradingSystemAbstract:Second-handbooksonlinebookstoresystembrokethetraditionalformsofsales,combinesabookshopandanetworkisakindoftypicalshoppingwebsiteuse.Second-handbooksonlinebookstoresystemisactuallyrunningonaWebserverinaWebapplication.Page,thescriptisusedtorealizethesaleofusedbooks,displays,purchasingandsupplyoperations,thissystemisinlinewiththetime,everyyeartherearealotofstudentsgraduateinourcountry,buttheyusesomeofthebooksnottoread,inordertobeabletomakethenextstudentbetterapplicationwedevelopedthissystemInthedevelopmentbackgroundofactualapplication,thispaperUSEStheprincipleofsoftwareengineeringanddevelopmentmethod,usingASP.NettechnologytobuildabasedonB/Smodelofsecond-handbooksonlinebookstoresystem.Throughoutthedevelopmentprocess,firstofall,onthesystemdemandanalysis,systemmainfunctions,dataflowdiagramsanddatadictionary.Thenthesystemoveralldesignanddetaileddesign.Overalldesignmainlyincludesthesystemfunctiondesign,systemoverallstructuredesign,systemdatastructuredesignandsystemsecuritydesign,etc.Thedetaileddesignmainlyincludestherealizationofthesystemdatabaseaccess,theconcreteimplementationofmainfunctionmodule,moduleimplementsthekeycode,etc.Finally,thesystemfunctionaltesting,andthetestresultsareanalyzedandsummarized,concludesthattheshortageofthesystemandtheneedtoimproveplace,convenienceisprovidedforfuturesystemmaintenance,butalsoforthefuturedevelopmentofsimilarsystemprovidesthereferenceandhelp.Thedevelopmentofthissystemmakesthesecond-handbooksonlinebookstoremanagementmoreconvenientandquick,atthesametimealsopromptedsecondhandbookonlinebookstoresystemismoresystematicandordering.Systeminterfaceisfriendly,easytooperate.Keywords:second-handbook,sales;ASP.Nettechnology;B/S目录1系统概述.....................................................11.1研究背景.......................................................................................................................11.2研究意义和现状...........................................................................................................11.3系统设计思想...............................................................................................................22系统开发环境.................................................32.1ASP.NET概述................................................................................................................32.2动态网站技术介绍........................................................................................................42.3数据库技术...................................................................................................................42.4ADO.NET连接数据库..................................................................................................53需求分析.....................................................63.1可行性分析....................................................................................................................63.1.1技术可行性........................................................................................................63.1.2经济可行性........................................................................................................63.1.3操作可行性........................................................................................................73.2系统用例........................................................................................................................73.3系统流程和逻辑............................................................................................................83.4计算机软硬件配置和开发平台..................................................................................103.4.1计算机系统硬件配置.......................................................................................103.4.2计算机系统软件配置.......................................................................................103.4.3编程环境与工具...............................................................................................104系统概要设计.................................................114.1概述.............................................................................................................................114.2系统结构.....................................................................................................................114.3.数据库设计...............................................................................................................124.3.1数据库E-R图..................................................................................................124.3.2
