PDM系统的体系结构分析及应用

浙江大学硕士学位论文AbstractiPDM系统的体系结构分析及应用摘要产品数据管理系统(ProductDataManagement，PDM)作为制造企业实施信息化的集成框架，已经被越来越多的企业所采用。根据企业的实际需求，要求PDM系统的开发由侧重于部门级的设计环节的数据管理与共享向贯穿企业全过程的企业级方向发展，要求系统能够充分集成现有的应用系统，对跨地域的产品数据同样实现信息集成，这就需要对PDM系统进行重新构架，本文就是基于这种背景下研究PDM的体系架构的。本文首先分析了PDM的产生背景、研究现状及其发展趋势，然后阐述了PDM中的关键技术，如成组技术、客户化技术、网络技术、集成技术等技术信息。接着本文研究了分布式PDM体系结构以及基于XML（ExtensibleMarkupLanguage）、基于J2EE的体系结构，阐述了各体系结构的组成及其优点，不同的体系结构适用于不同的企业对象，根据企业的实际需求选择不同的体系结构，更有利于企业PDM系统的实施。最后本文介绍了一款较为成熟的PDM系统——Teamcenter，分析了Teamcenter的体系架构，这种体系架构具备了强大的二次开发功能，本文根据某企业的实际需求，提出了对Teamcenter的数据管理部分功能进行二次开发的实施方案，并对其在客户端和服务器端的配置及操作进行了详细的说明。关键词：PDM，架构，分布式，XML，J2EE，Teamcenter浙江大学硕士学位论文AbstractiiAbstractProductdatamanagementsystem(ProductDataManagement,PDM)asanintegrationframeworkofthemanufacturingenterprisestoimplementinformation,hasbeenadoptedbymoreandmoreenterprises.Accordingtotheactualneeds,itdemandsPDMsystem’sdevelopfromfocusingonthedesignaspectsofdepartmentalmanagementandsharingofdatathroughouttheenterprisetothewholeprocessofenterprise-leveldirection,itrequiresthatthesystemcanfullyintegratewithexistingapplicationsystems,andimplementationinformationintegrationoftheproductdataoncross-boundary,thisneedsthePDMsystemtoberestructured,basedonthisbackground,thisarticleinvestigatethearchitectureofPDM.Firstthisarticleanalysestheproduction,developmentofthePDM,andthendescribesthekeytechnologiesofthePDM,suchasgrouptechnology,customizedtechnology,networktechnology,integrationtechnologyandsoon.ThenthisarticleinvestigatesthedistributedPDMarchitectureandthearchitecturewhichbasedonXML(ExtensibleMarkupLanguage)andJ2EE,alsoitdescribesthecompositionofeachsystemanditsadvantages,accordingtotheactualneedsofenterpriseschooseadifferentarchitectureismoreconducivetoimplementthePDMSystem.Finally,thepaperdescribesamaturePDMsystem–Teamcenter,analysesthearchitectureofit.ThearchitectureofTeamcenterhasastrongsecondarydevelopmentfunction,accordingtotheactualneedsofanenterprise,thispapermadeanimplementationplanforthesecondarydevelopmentpartoftheTeamcenterdatamanagementfunction.KeyWords：PDM,Architecture,distributed,XML,J2EE,Teamcenter浙江大学硕士学位论文目录I目录摘要...............................................................................................................................iAbstract........................................................................................................................ii图目录........................................................................................................................III表目录.......................................................................................................................IV第1章绪论................................................................................................................11.1研究背景.............................................................................................................11.1.1PDM的产生背景..........................................................................................11.1.2PDM与企业信息管理..................................................................................21.2研究的意义.........................................................................................................31.3本章小结.............................................................................................................4第2章相关技术综述................................................................................................52.1PDM概述.............................................................................................................52.1.1PDM简介......................................................................................................52.1.2PDM的产生发展及应用..............................................................................62.1.3PDM的研究现状..........................................................................................72.1.4PDM技术的发展趋势..................................................................................72.2PDM中的关键技术.............................................................................................82.2.1成组技术......................................................................................................82.2.2客户化技术..................................................................................................82.2.3流程的设计方法..........................................................................................92.2.4数据存储与管理..........................................................................................92.2.5系统集成....................................................................................................102.2.6网络技术.....................................................................................................112.3本章小结...........................................................................................................12第3章分布式PDM系统的通用体系结构............................................................133.1C/S体系结构.....................................................................................................133.2多层体系结构.............................
