内容摘要在科学技术日新月异的今天，计算机已逐步渗入各个领域，无论是学习，工作，还是娱乐都普及了计算机的使用，而随着网络的开通、并与Internet连接更让我们社会成为信息化的时代，人们不再需要浪费太多的时间去手工的获得信息，只要做在家中轻点几下鼠标不但能轻松获得各种信息，而且能够购买到自己需要的商品，既摆脱了时间和空间的限制又节约了大量的时间，因此熟练使用计算机及网络，已成为人们进入现代社会的必备技能。商品销售管理系统正是在这种情况下诞生并逐渐发展起来的，它已成为我们进行商品交易中不可缺少的部分。商品信息管理系统是典型的信息管理系统(MIS),其开发主要包括后台数据库的建立和维护以及应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的数据库，而对于后者则要求应用程序功能完备,操作简单等。本系统是在分析了现行商品管理中存在的问题的基础上，结合信息管理系统开发的概念、结构及系统开发的基本原理和方法，开发的一套商品信息管理系统。根据实际情况，由目前各功能需求和公司里的情况而设计的这套系统。全文共分为课题研究的意义、开发环境、系统的实现、性能测试与分析以及结束语等章节，详细地阐述了本系统开发的目的、过程。关键词：信息管理系统；系统开发；商品销售AbstractTherapidadvanceofscienceandtechnologytoday,thecomputerhasgraduallyinfiltratedallareas,regardlessoflearning,work,orentertainmentthroughoutallofthecomputer'suse,andwiththeopeningofnetworks,connectingwiththeInternetandmadeusbecomeinformation-basedsocietyofthetimes,Peoplenolongerneedtowastetoomuchtimeformanualaccesstoinformation.AslongasitisathomeClickonthemouseandunderstandworld,buttobuytheirneedsofcommodities,bothoutoftimeandspaceconstraintstosaveaIIgreatdealoftime,theuseofskilledcomputerandnetwork,Peoplehavebecomemodernsocialskillsrequired.SalesManagementSystemisundersuchcircumstancesbirthandgraduallydevelopsandithasbecomeacommoditytransactionsindispensablepart.CommodityinformationmanagementsystemistypicaloftheInformationManagementSystem(MIS),includingdevelopmentofitskeydatabasebackgroundtotheestablishmentandmaintenanceoffront-endapplicationsandthedevelopmentofthetwoareas.Regardingtheformerrequirementtoestablishdataconsistencyandintegrityofstrong,gooddatasecuritydatabase.Asforthelatterdemandedtheapplicationfunctions,andsimpleoperation.Thesystemistheanalysisoftheexistingmerchandisemanagementproblemsthatexistonthebasisofacombinationofinformationmanagementsystemsdevelopmentconcepts,structureandsystemdevelopmentandthefundamentalprinciplesandmethods,developedasetofcommodityinformationmanagementsystem.Accordingtotheactualsituationfromthevariousfunctionalneedsandthesituationofthecompanyandthedesignofsuchsystems.Thearticleconsistsofthesignificanceoftheresearch,developmentenvironment,therealizationofsystemperformancetestsandanalysis,andconclusion,thechapters,detaileddescriptionofthepurposeofthesystemdevelopmentprocess.KeywordsInformationManagementSystem;SystemDevelopment;Commoditysales1目录第一章：引言....................................................11.1信息管理系统简介......................................................11.2本课题研究的意义......................................................11.3系统研究设计的目标....................................................2第二章现行系统调查研究.....................................................22.1现行业务介绍..........................................................22.2该企业的组织机构图....................................................32.3新系统业务流程图......................................................32.4可行性分析............................................................52.4.1技术可行性.....................................................52.4.2经济可行性.....................................................52.4.3操作可行性.....................................................5第三章系统分析.............................................................63.1数据流程图............................................................63.2数据字典..............................................................93.2.1数据元素卡.....................................................93.2.2数据流卡......................................................113.2.3数据处理卡....................................................133.2.4数据存储卡....................................................13第四章系统设计............................................................164.1系统结构设计.........................................................164.1.1系统结构图....................................................164.1.2系统模块图....................................................174.2代码设计.............................................................204.3输出设计.............................................................204.4输入设计.............................................................2124.5数据库的设计.........................................................224.5.1数据库需求分析................................................224.5.2数据库逻辑结构设计............................................234.5.3数据库的备份和恢复............................................24第五章系统实施...........................................................255.1语言的选择...........................................................255.2系统的运行环境.......................................................255.3程序完成情况表.......................................................255.4界面设计及程序设计...................................................26第六章系统使用与评价......................................................316.1本系统的使用方法.....................................................316.2系统评价.............................................................34结论.......................................................................34致谢........................................................错误!未定义书签。参考文献...................................................................35附录...................
