区域气象自动站的建立,提高了防灾减灾及突发灾害性天气的监测预警能力。随着站点建设规模的快速扩展,数据处理量成倍增多,对数据库系统的存储处理提出了更高的要求。ORACLE数据库在处理海量数据方面,性能优异、可伸缩性强。以ORACLE 10G作为核心数据库,设计、建立了基于ORACLE的陇东南区域自动气象站数据库与应用系统。经过试用表明,该数据库能够很好地满足区域自动气象站数据实时访问和检索需求,提高了数据应用效率,实现了陇东南和周边部分地区近千个站点的资料自动入库、存储和查询检索。本文对数据库设计、SQL语句查询优化原则、ORACLE 数据服务器和客户端的连接配置等方面做了重点介绍。
區域氣象自動站的建立,提高瞭防災減災及突髮災害性天氣的鑑測預警能力。隨著站點建設規模的快速擴展,數據處理量成倍增多,對數據庫繫統的存儲處理提齣瞭更高的要求。ORACLE數據庫在處理海量數據方麵,性能優異、可伸縮性彊。以ORACLE 10G作為覈心數據庫,設計、建立瞭基于ORACLE的隴東南區域自動氣象站數據庫與應用繫統。經過試用錶明,該數據庫能夠很好地滿足區域自動氣象站數據實時訪問和檢索需求,提高瞭數據應用效率,實現瞭隴東南和週邊部分地區近韆箇站點的資料自動入庫、存儲和查詢檢索。本文對數據庫設計、SQL語句查詢優化原則、ORACLE 數據服務器和客戶耑的連接配置等方麵做瞭重點介紹。

Because of regional automatic meteorological stations,the ability of monitoring and early warning of disaster prevention and mitigation of severe weather emergencies has been promoted.But with the rapid expansion of the automatic weather stations,the data processing increases exponentially,so the higher requirements for storage processing of database system are put forward.ORACLE da-tabase has so many advantages in dealing with massive amounts of data,such as excellent performance and strong scalability.The re-gional automatic meteorological station database application system in southeast Gansu was designed and established based on ORACLE 10G.The tryout showed that this system could satisfy the requirement of visiting and searching real-time data of regional automatic meteorological stations,the application efficiency has been improved,and the data from thousands of regional automatic meteorological stations which located in southeast Gansu and surrounding areas could realize automatically warehousing,store,search and retrieve.In this essay,the design,optimization principles of statement query,connection configuration of ORACLE data server with client of the database have been introduced.
