針對虛擬企業(yè)對異構(gòu)分布性信息資源集成的要求，提出了一個基于元數(shù)據(jù)和Web service 的虛擬企業(yè)信息集成框架。詳細(xì)分析了信息集成協(xié)議棧的層次結(jié)構(gòu)，給出虛擬企業(yè)服務(wù)共享方案和數(shù)據(jù)共享系統(tǒng)結(jié)構(gòu)。本信息集成框架克服了傳統(tǒng)跨平臺技術(shù)及數(shù)據(jù)共享技術(shù)在實現(xiàn)虛擬企業(yè)信息集成中的局限。

Abstract: This paper presents a framework of Virtual Enterprise (VE) information integration based on metadata and WebService technology to realize the isomeric and distributed information resources integration in VE. The information integration protocol stack is analyzed in detail. And the VE services sharing scheme and VE data sharing system architecture are given out. The limitations of traditional across-platform technology and data sharing technology are overcome by this framework, which adapts well to the requirements of VE information integration.
