摘要
在实际应用环境中,网格数据管理需要集成已有的数据库.以油气勘探开发领域中分布、异构、自治的已有数据库信息源为主要研究对象,采用多代理技术,提出了一种基于网格中间件基础数据管理功能的网格数据集成中间件.详细阐述了中间件核心模块——集成访问代理的结构模型,给出了代理间传递的消息格式,论述了代理间的通信协作方法.
In a specific application domain,the grid data management needs to integrate existing databases.The distributed,heterogeneous and autonomous existing databases in the field of oil & gas exploration and development being taken as main study objects,a grid data integration middleware based on the basic data management function of a grid middleware is put forward by means of multi-agent technique.The structure model of the integration and access agent,the key module of the middleware,is discussed in detail.The message passing format and the communication and cooperation method between agents are presented.
