一种面向水利网格醮数据中心设计与开发

针对网格环境中信息服务模式的缺陷，并结合当前水利数据管理领域存在的问题，设计出一种采用改进三角式信息服务模型的面向水利网格的数据管理平台——数据中心。数据中心以元数据服务和数据代理为关键技术。通过建立水利元数据模型以及提供基本数据注册发布、基本数据访问等服务，解决了异构数据集成和分布式数据访问的问题。最后介绍了数据中心的开发。

Design and development of water-related data center: on the basis of grid

Aiming at upgrading the current models of information service in grid environment and problems existed in the domain of water data management, a water data management platform - data center based on the improved triangle-model and water grid is put forward and designed by using metadata services and data agent as key technologies, for building water metadata model and providing services with fundamental data registrationpublishing and fundamental data accessing, in order to resolve the problems such as integration and distributed sharing in heterogeneous data. Finally the development process of data center is introduced.
