大型图书馆图书借阅系统设计摘要：图书借阅系统采用三层B/S模式，具有操作方便、界面友好的优点。在系统设计中采纳VisualStudio2010（C#）开发、SQLServer2008数据支撑。本系统适合于大型图书馆图书信息管理系统，用于摆脱一系列人工管理的内在问题。用户可以短时间内找到要借阅的图书，同时它具有动态，及时调整文档结构的功能，使图书馆正在逐步向计算机信息化管理转变。包含六个功能模块，信息管理，用户管理，图书馆，图书检索，系统管理和系统辅助。在本系统的实现中，采用了多种查询技术；为提高系统的网上检索的效率，对查询结果采用缓存技术和其它的系统优化技术。同时在开发中采取了安全性措施，确保了系统在一定程度上的安全可靠。前言叙述了图书馆管理现状以及用计算机管理图书馆的前景。对系统的设计思想和模块化设计的基础文本，文档管理系统的可行性分析，数据库设计，系统设计，系统的维护和改进作参考。关键词：图书借阅系统VisualStudio2010SQLServer2008Asp.NetLargelibrarybooklendingsystemdesignAbstract:LibrarysystemadoptsthreelayerB/Smode,possessestheadvantagesofconvenientoperation,friendlyinterface.InsystemdesigntoadopttheVisualStudio2010(c#)development,SQLServer2008datatosupport.Thissystemissuitableforlargelibrarybookinformationmanagementsystem,isusedtogetridofaseriesofinternalproblemsofartificialmanagement.Userscanfindtoborrowbooksinashortperiodoftime,atthesametimeithasdynamic,timelyadjustthestructureofthedocumentfunction,makethelibrarytocomputerinformationmanagement.Containssixfunctionmodule,informationmanagement,usermanagement,library,booksretrieval,systemmanagementandsystemsupport.IntheimplementationofthissystemUSESavarietyofquerytechnology;Inordertoimprovetheefficiencyoftheonlineretrievalsystem,withtheresultofthequerycachetechnologyandothersystemoptimizationtechnology.Indevelopingsecuritymeasuresweretakenatthesametime,toensurethesystemtoacertainextent,safeandreliable.Theforeworddescribesthelibrarymanagementstatusquoandtheprospectofthemanagementofthelibrarybycomputer.Onthesystemdesignandmodulardesigntext,thebasisofthefeasibilityanalysisforthedocumentmanagementsystem,databasedesign,systemdesign,systemmaintenanceandimprovementforreference.Keywords:BooklendingsystemSystem;VisualStudio2010;SQLServer2008;Asp.Net目录1前言........................................................................................................................................11.1问题的提出.................................................................................................................11.2需求分析.....................................................................................................................12设计思想及依据....................................................................................................................22.1设计思想.....................................................................................................................22.2开发工具介绍.............................................................................................................23系统可行性分析....................................................................................................................33.1结构的选择（B/S）...................................................................................................33.2技术可行性.................................................................................................................33.3经济可行性.................................................................................................................33.4操作环境及运行环境.................................................................................................44总体设计................................................................................................................................54.1项目规化.....................................................................................................................54.2系统功能结构图.........................................................................................................55公共类设计............................................................................................................................76数据库设计............................................................................................................................96.1数据库概要说明.........................................................................................................96.2数据库概念设计.........................................................................................................96.3数据逻辑结构设计...................................................................................................127模块设计..............................................................................................................................137.1用户管理模块...........................................................................................................137.2图书信息管理模块...................................................................................................137.3图书借阅模块...........................................................................................................167.4图书查询模块...........................................................................................................197.5系统辅助模块...........................................................................................................207.6系统管理模块...........................................................................................................218网站的编译和发布.......................................................................................................
