THE CONSTRUCTION Of NATIONAL METEOROLOGICAL ARCHIVAL AND RETRIEVAL SYSTEM

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.
