【摘要】 在分析产品数据管理结构和功能特点的基础上,根据动态企业联盟、虚拟公司的兴起以及数字化制造技术的发展,分析了产品数据管理的发展方向。并且在分析传统Web化的产品数据管理系统集成中有关问题的基础上,建立了一个基于Web技术的四层分布式产品数据管理集成系统的网络架构,阐述了这种体系结构轻型、开放性强的优点和实施中的松耦合、联机事务处理等关键技术,测试结果表明系统功能完整、性能稳定、运行良好。更多还原

【Abstract】 On the basis of analyses of structure and function characteristics of Product Data Management(PDM),according to the fast development of the dynamic coalition of companies,virtual company and the development of the digitized manufacturing technology,the developing direction of PDM is analysed and the relevant questions of PDM system integration on traditional web are discussed.One 4-tier distributed PDM system on the basis of web technology is set up.The advantage of the light system structure,and openness and the key techniques of loose coupling,web OLTP with it are also discussed.The test shows that the systematic functions are complete and the system performs well with stability.更多还原
