一种地市级气象数据库的设计与应用

面向地市级气象业务数据库系统存在的数据管理分散、数据流程不统一等问题，以气象数据为核心，从标准化、规范化数据库建设的角度，提出一种气象数据库系统架构与设计方法。从逻辑结构、物理存储方面对气象数据进行划分，设计了气象数据的物理存储模型和数据统一访问规范。基于RabbitMQ消息中间件和元数据技术实现了多种气象观测资料的采集、传输、入库、备份的统一处理。通过消息数据与元数据的映射关系，增强了多源气象数据处理的灵活性和可扩展性。该系统已经投入业务使用，为气象数据管理和公共服务提供稳定、高效的数据支撑，取得较好的应用效果。

Design and Application of Prefectural Level Meteorological Database

Concerning the difficults in data management and organization of prefecture level meteorological database systems,a novel approach for architecture and design of meteorological database system is presented under the framework of standardization and normalization. The physical storage model and uniform interface specification of meteorological data are designed through the logical and physical classification of those data. In addition, to archive a uniform treating effect of meteorological data acquisition, transmission, storage, and backup, a data processing method is presented based on RabbitMQ and metadata technology, which enhances the flexibility and extensibility of meteorological data processing through the mapping relationship of message data and metadata. The system has been put into operation, which provides stable, efficient data support for meteorological data management and public service.
