【摘要】 根据"十五"中国地震前兆信息网络建设的需要,在全国地震系统中实现地震前兆数据的自动化交换管理。我们分析提取出地震前兆元数据的管理模型并基于Oracle快照复制技术设计和实现了地震前兆元数据的交换管理。本文对Oracle快照复制技术做了较为详细的介绍,并分析指出了Oracle快照复制技术应用于地震前兆元数据交换的关键点,结合数据管理系统在地震前兆中的实际使用情况做了简要讨论。实践证明,基于Oracle快照复制技术实现的地震前兆台网数据管理系统软件完全满足了地震前兆网络建设的需要。更多还原

【Abstract】 The construction of the China Earthquake Precursor Information of 10th "Five-Year Plan" sets a demand on the automatic exchange of the China earthquake precursor data in the national seismic system and facilitates the share of data among earthquake researchers. This paper builds up a model of earthquake precursor metadata and designs and realizes the management of the exchange of earthquake precursor data with the help of the Oracle snapshot replication technology. The paper gives a detailed introduction to the Oracle snapshot replication technology, analyzes the key points in the application of this technology to the exchange of earthquake precursor metadata and briefly discusses the actual application of the technology in the earthquake precursor data system. There is evidence that the Oracle snapshot replication based system of the earthquake precursor metadata exchange can well meet the needs of the development of the Earthquake Precursor Exchange System.更多还原
