基于网格服务的分布式异构数据集成研究

随着作战指挥训练模拟系统的快速发展和应用,如何访问和操作早期建设的异构的分布的基础数据资源,是当前急需解决的问题。在分析了现有异构数据集成系统不足的基础上,通过引入网格服务技术,提出了一个基于网格的分布式异构数据集成模型。同时引入基于元模型的元数据目录服务技术,一定程度上解决了数据集成中的语义冲突的问题,使异构数据集成更加高效。最后通过一个应用实例验证该模型的可行性。

The Research about Military Training Date Integration Bases on Grid Service

Along with the rapid development of the Simulation Training System for Commander of Combat, How to access and manipulate the distributed heterogeneous data resource is the essential point. A grid-based integration model of distributed heterogeneous data is present based on the analysis of the shortcomings of the existent heterogeneous data integration system. Using the metadata directory service based on metamodel, it can solve the semantic conflict during the process of data integration, and make the integration more effective. Finally, an example is achieved.
