基于网格的标准件库系统研究与开发

网格服务实现以本地平台基础设施与已有IT基础设施相结合为目标,基于网格的标准件库系统旨在整合众多现有的标准件库资源。基于开放网格服务体系结构提出了标准件库网格服务的功能模型,通过定义标准件库系统与外界进行信息交换的行为接口,避免系统与外界直接进行信息交互。现有的标准件库系统只需提供服务的行为接口即可方便地部署到互联网中,充分发挥了网格集成和共享资源的优势,为解决大量的企业标准件库系统重复开发问题提供了可行的方案。最后实现了基于UG II和SQL Server2000的标准件库网格服务节点,提供标准件的查询、下载及模型在线浏览等服务。

Research and Development of Grid Standard Part Library System

The goal of realizing grid services is to interconnect local infrastructure resources and existing information technology infrastructures.The grid-based standard part library system aims to integrate standard part library resources.A function model of grid standard part library system is proposed on the basis of open grid services architecture(OGSA).In this model,the local standard part library system does not exchange information directly with its client side through defining the behavior interfaces between them.Existing standard part library systems can be easily linked to Internet just by providing the behavior interfaces of the services,taking fully advantages of integration and sharing of resources by grid and of systems which offer a feasible scheme for solving the problem of repeatedly developing enterprise standard part librarces.Eventally a standard part library system supported by Unigraphics18.0 and SQL Server2000 is implemented as a standard part library grid service node,providing such standard part services as inquiry,downloading and model view online.
