摘　　要：网格技术越来越多的应用于仿真领域中。仿真程序包含很多数据密集型应用,它们需要使用大量分布的数据库资源。如何访问和操作这些异构的数据库资源是应用程序的关键问题。在利用现有的访问网格中异构数据源方法的基础上,提出了基于网格服务的异构数据源集成体系结构,可以在应用过程中动态绑定数据源;同时在选择数据服务的时候采用基于Qos的选择模型,可以有效的避免服务失效的现象。Simulation grid is an application of grid and modem simulation and model technology. Many data-intensive applications require a lot of distribute and heterogonous data resources. So it is crucial for these applications of how to access and operate these data resource. Architecture of the data integration system for the distributed and heterogonous data resources was proposed based on the grid, through which the application can find and bind the data resource at the moment of need. And irr the processing of choosing the data resources, the model based on Qos was adopted, which can avoid the fail of data resources effectively.
