国家级气象资料存储检索系统的建立

THE CONSTRUCTION Of NATIONAL METEOROLOGICAL ARCHIVAL AND RETRIEVAL SYSTEM

对国家级气象资料存储检索系统的需求进行了分析 ,进而对系统进行了功能设计 ,并在技术调研和分析的基础上确定了功能实现的技术路线 :在数据管理方面采用数据库和文件系统相结合的方式 ;在存储管理方面采用分级存储管理模式 ,并解决了数据库的分级存储管理技术 ;在检索应用方面提供了程序调用式检索方式 ,并通过采用中间件技术实现了基于B/S结构的程序调用式检索 ;通过选用HPSS技术解决了由异种机型构成的高性能计算机群存储池问题 ;通过分别建立实时数据库和综合数据库解决了气象资料的规范化存储和实时业务使用需求之间的矛盾 ;

The system requirements of NMARS (National Meteorological Archival and Retrieval System) and the function designs for the system are suggested. Based on the technique investigation and analysis, the technique schemes for the implementations of those functions are also given: the RDBMS integrated with the external file system is used for data management; the HSM (Hierarchical Storage Management) architecture is adopted for storage management, including the storage management of RDBMS; the program-retrieval function is provided for data retrieval. In terms of the middleware technology, the realization of the function is based on the B/S (Browser/Server) architecture; the HPSS (High Performance Storage System) solution is applied in the storage pool issue of the HPC (High Performance Computer) cluster system composed of several HPCs with different architecture; the RDB (Real-time Database) system and IDB (Integrated Database) system are designed to solve the contradictory between the standardization storage of the meteorological data and the performance requirements of the real-time operational system; the corresponding specifications are strictly followed in software development.
