摘要
为建立一种柔性、自适应的IT基础设施来实现随需的企业信息动态集成,提出一种面向对等语义网格服务的企业信息集成方法。该方法在结合基于对等网络的数据集成范例与语义网格技术的基础上,定义了四种面向不同语义描述层次的节点,通过节点之间的语义映射建立多层次、多粒度的企业数据对等语义集成框架;以扩展网格服务接口和建立语义元数据为手段,将每个节点转化为一个语义网格服务,将节点间的互操作转化为语义网格服务的互操作,实现基于对等网络语义互联的逻辑集成架构到面向语义网格服务体系的物理集成架构的映射,以及支持大规模、跨领域的面向对等语义网格服务的企业信息动态集成。
To establish a more flexible and adaptive IT infrastructure so as to realize enterprise information integration dynamically on demand,a Peer to Peer（P2P） Semantic Grid service oriented enterprise Information Integration（SGII） approach was proposed.In this approach,four kinds of peers were defined and a multilevel multi-granularity P2P semantic integration architecture was established through semantic mapping among peers.By extending grid service interface and using metadata,each peer was converted to a semantic grid service,and the interoperations among peers were translated into those among semantic grid services.Mapping from P2P-semantic-cooperation-based logic integrated architecture to semantic-grid-service-oriented physical integrated architecture was realized.Finally,the large scale and cross-area SGII was implemented.
