摘要
为解决目前大规模仿真系统中对于分布、异构的数据资源进行统一访问和控制的问题,提出了一种仿真网格系统中数据集成和访问的框架,阐述了该框架下的OGSA-DAI的实现机制,并结合XML分析了数据集成和访问的原理。结合OGSA-DAI,给出了仿真数据资源集成和访问的具体实现方法。在仿真网格环境下,通过仿真网格数据库的构建实现对分布、异构的仿真数据、模型资源的动态分配和多用户的并发访问。
To address the issues of controlling and accessing the different types of distributed data resources in the simulation system, a frame of data integration and access in the simulation grid system was proposed. The mechanism of OGSA-DAI was discussed. Combining XML, the principle of data integration and access was analyzed and a way to solve this problem in the simulation grid system was provided. The databases in the simulation grid system supported the dynamic distribution of the data and model resources in the simulation environment. It also realized the multi-user database accessing concurrently.
