基于网格的水利数据中心数据集成研究

Research on Data Integration of Water Resources Data Center Based Grid Technology

本文以实时雨水情数据为例,采用网格技术设计思想研究水利数据中心中异构数据库的数据集成方案。通过确定数据访问策略、定义元数据字典和开发相应的软件来实现分散存储数据的集成访问及应用。通过对分布在不同节点的异构化实时雨水情数据库进行查询的软件系统设计与开发验证了集成方案的可行性。

In this paper, the real-time hydrological information database was taken as an example. The integration scheme of heterogeneous databases of water resources data was researched with the design concept of grid technology. The data access strategies, metadata dictionary, software module development was suggested. The database integration was executed between the databases which spread around basin organization, province and etc. Design feasibility was validated by experimentation of real-time hydrological information data querying.
