I摘要进销存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前端应用程序的开发两个方面.对于前者要求建立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,易使用等特点。经过分析如此情况,我们使用SQLserver2000作为后台数据库,VB作为数据库系统开发工具,利用其提供的各种面向对象的开发工具,尤其是数据窗口这一能方便而简洁操纵数据库的智能化对象,首先在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成用户满意的可行系统。【关键词】面向对象企业资源计划数据库管理信息系统IIAbstractStockandsellInfomationManagementSystemisdevelopmenttwoaspectsthattypicalinformationmanagementsystemMIS,itsdevelopmentincludesprimarilythebackstagedatabaseestablisheswithsupportandtheheadappliesthedevelopmenttwoaspectsoftheprocedure.Establishthedataconsistencytotheformerrequestisstrongwiththecomplete,thethatdatasafetygooddatabase.Butrequestthelatterverymuchtheappliedprocedurefunctioncomplete,easyusageetc.characteristics.Throughtheanalysissuchcircumstance,weusetheACCESSasthebackstagedatabase,andtheVBasdatabasedevelopmenttool,makeuseofitseverykindofthetoolofdevelopmentthatprovidethatfacetotheobject,particularlyisintelligencethatdatawindowwaythisoncanningbeconvenientbutconciselymanipulatesthedatabaseturntheobject,establishintheinashorttimefirstsystemapplicationprototype,then,starttothebeginningprototypesystemproceedingneediterationonbehalf,revisecontinuouslywithimprove,reallyarrivetobecomethecustomersatisfiedcanAsystem.【Keywords】facetotheobjectenterpriseresourceplanningdatabasemanagementinformationsystem.III目录摘要...................................................................................................................IABSTRACT.............................................................................................................II第1章绪论.......................................................................................................11.1选题背景.....................................................................................................11.2论文的意义.................................................................................................11.3论文的目的.................................................................................................11.4国内外研究现状.........................................................................................2第2章相关理论研究.......................................................................................32.1管理信息系统的基本含义.........................................................................32.2管理信息系统的功能.................................................................................32.3ERP概述.....................................................................................................42.4数据库理论概述.........................................................................................52.5技术方案的选择.........................................................................................62.5.1开发环境.............................................................................................62.5.2性能需求.............................................................................................62.5.3运行环境.............................................................................................7第3章系统分析.................................................................................................83.1系统开发的必要性分析.............................................................................83.2系统的初步调查.........................................................................................83.3系统开发的可行性分析.............................................................................93.4组织结构分析...........................................................................................113.5业务流程分析...........................................................................................123.6数据流程图...............................................................................................153.7数据字典...................................................................................................173.7.1数据项的描述...................................................................................173.7.2数据结构的描述...............................................................................193.7.3数据流的描述...................................................................................203.7.4处理逻辑的描述...............................................................................213.7.5数据存储的描述...............................................................................223.7.6外部实体的描述...............................................................................23IV3.8系统开发方法...........................................................................................233.9系统开发计划...........................................................................................24第4章系统设计...............................................................................................254.1总体设计...................................................................................................254.2输入设计...................................................................................................264.2.1输入设计的原则...............................................................................264.2.2输入设计的内容.......................
