中小企业ERP管理系统--销售管理子系统的设计与实现

本科毕业设计题目：中小企业ERP管理系统--销售管理子系统的设计与实现中小企业ERP管理系统--销售管理子系统的设计与实现摘要：当今的社会经济与信息技术飞速迅猛发展，中小型企业的销售管理系统决定了一个企业能否盈利，也是一个中小型企业发展和经营的关键。ERP系统的方便快捷，省时省力，几乎所有企业都会用到ERP系统。本文的系统主要使用J2EE的SSH框架做后台、ExtJS做前台。struts框架来做应用层，主要负责调用业务逻辑service层；hibernate框架用来做对象关系映射以及操纵数据库；spring框架用来做管理的容器，管理框架和框架；ExtJS用来做前端界面，实现交互。该系统是根据中小企业中对销售单据和退货单据的记录，销售记录和退货记录查询的实际需求，方便实现了单据生成和存储的功能。具体实现了商品销售流程的处理，销售单据的以及单据的生成、查询和删除功能。还实现了客户退货的处理，客户退货单据的生存、查询和删除功能。用户可以随时在计算机上涌浏览器登陆系统进行管理，实现单据记录的简单方便化，提高企业工作效率，提高查询速度，实现企业的高效管理。关键词：ERP；销售管理；SSH；ExtJSThesmallandmedium-sizedenterpriseERPmanagementsystem,salesmanagementsubsystemAbstract:Today'ssocialeconomyandtherapiddevelopmentofinformationtechnology,thesalesmanagementsystemofsmallandmedium-sizedenterprisesenterprisescandetermineaprofit,butalsothesmallandmediumenterprisedevelopmentandmanagementofthekeya.TheERPsystemisconvenient,time-savingandlabor-saving,almostallenterpriseswillusetheERPsystem.TheSSHframeworkinthissystemmainlyuseJ2EEasbackground,theExtJSasthefront.Thestrutsframeworktodotheapplicationlayer,businesslogiclayerisresponsibleforcallingservice;Hibernateframeworkforobjectrelationalmappinganddatabasemanipulation;springframeworkformanagementofcontainer,managementframeworkandtheframework;andExtJSwasusedasthefront-endinterface,interactive.Thesystemisbasedontherecordofsalesdocumentsandreturnthedocumentsinthesmallandmedium-sizedenterprises,theactualdemandsalesrecordsandreturnrecordsquery,tofacilitatetherealizationofthedocumentgenerationandstoragefunction.Theconcreterealizationoftheprocessofcommoditysalesprocess,salesdocumentsanddocumentgeneration,queryanddeletefunction.Alsothehandlingofcustomerreturn,customerreturnsdocumentssurvive,queryanddeletefunction.Theusercanatanytimeinthecomputerupwellingbrowserlandingsystemsmanagement,simpleandconvenientrealizationofdocumentrecords,improvetheworkingefficiencyofenterprises,improvethequeryspeed,toachieveefficientmanagementofenterprises.Keywords：ERP；marketingmanagement；SSH；ExtJS目录一、引言................................................1（一）选题背景........................................................................................................1（二）主要研究内容................................................................................................1（三）涉及的技术和框架........................................................................................2二、可行性分析..........................................5（一）经济可行性....................................................................................................5（二）技术可行性....................................................................................................5（三）运行可行性....................................................................................................5（四）法律可行性....................................................................................................5三、需求分析............................................6（一）业务流程分析................................................................................................6（二）系统功能模块需求分析................................................................................8（三）非功能需求分析............................................................................................9（四）系统开发环境................................................................................................9四、系统概要设计.......................................10（一）总体功能结构设计......................................................................................10（二）数据初步库设计..........................................................................................11（三）E-R图...........................................................................................................12五、系统详细设计.......................................16（一）数据库逻辑设计..........................................................................................16（二）各功能模块详细设计..................................................................................19（三）数据流图......................................................................................................21（四）程序流程图..................................................................................................22六、系统实现...........................................29（一）商品销售功能..............................................................................................29（二）客户退货功能..............................................................................................33（三）销售单据查询功能......................................................................................35（四）退货单据查询功能......................................................................................37（五）实现总结......................................................................................................38七、系统测试...........................................39（一）测试的作用..................................................................................................39（二）测试需求......................................................................................................39（三）性能测试......................................................
