水利数据多库智能整合机制研究与应用

Research and application of intelligent multi-databases integration mechanism for water resources data

面向多种水利要素的整合应用需求,结合水利数据分库独立管理的特点,提出水利数据多库智能整合机制,利用统一数据资源索引模型对异构的水利业务数据进行一体化描述与整合,支持异构数据库的接入与动态扩展,并提出水利数据整合资源的服务工作流,为水利数据资源的有效整合提供可行的思路。该机制在长江水文资源整合和应用服务系统中得以验证,可实现多个水利业务数据库的整合,极大提升水利数据的管理和服务效率。

Orienting to the integrated application needs for multiple water resources elements,this paper proposes an intelligent multi-databases integration mechanism for water resources data,which is combining the feature that water resources data are managed by different databases.The method uses uniform data resource index model to describe and integrate heterogeneous water resources data,and supports heterogeneous databases switch-in and dynamic expansion.This method also puts forward a service work flow for integrated water resources data resources,and is a feasible way for the integration of water resources data.This mechanism has been used and verified in Changjiang River hydrology resource integration system and application service system,which realizes the integration for diverse water resources bossiness databases and enhances the management power and service efficiency greatly.
