省级防汛指挥系统数据分布策略与元数据库

Provincial Flood Control System Data Distribution Strategy and Meta-database

在分析省级防汛指挥系统数据库的层次特征、数据采集点、地市及省数据中心的数据传输、检索与更新需求的基础上,设计了支持横向分片与混合型分配的多数据库系统的元数据库,提出了基于元数据库的省、地数据中心数据的分布策略。

Based on the analysis of database hierarchy, collection spot, information communication, data searching and updating requirement for the provincial flood control system, a metadatabase of multidatabase system supported by transverse dataslicing and mix distributing is designed. The data distribution strategy based on metadata of city and provincial information centers is proposed and applied in Hubei Provincial Flood Control System.
