网格环境下基于P2P的数据集成方法

Data Integration Method Based on P2P in Grid Environment

针对旧有数据集成方法已不适应网格环境下高动态数据集成的现状,提出基于P2P的数据集成方法,给出一个异构的XML数据源的集成框架。通过在各Peer点直接建立模式映射,利用给出的分解再组成算法,有效地完成对各网格节点上动态XML数据源的集成。

Aiming at the actual instance that old existed methods of data integration are not suitable to the high dynamical data integration in grid environment, this paper proposes a new method of data integration based on P2P and gives an integration framework of heterogeneous XML data resources. By establishing schema mappings directly at different Peers and using the decomposation-reform algorithm, the dynamical XML data resources on different gird nodes are integrated efficiently.
