摘要: 介绍了首都圈地震前兆数据库系统的数据库平台、数据库结构以及数据汇集与共享服务, 给出了首都圈地震前兆数据库系统数据库复制的维护经验。为保障首都圈二市一省的数字化前兆数据能及时、连续地汇集到首都圈地震前兆台网中心, 研制了一个数据传送软件, 以便在数据库复制出现故障时将数据从二市一省前兆台网中心传送到首都圈地震前兆台网中心。该软件的主要功能包括数据传送、数据显示和图形显示。

Abstract: In this paper, we briefly introduce the platform and structure, data collection and sharing services of the system of earthquake precursory database in the capitalarea.We also describe in detail the experience of maintenance of database replication.In order to ensure that the digital observational data in the capital area could be collected from the databases of the Center of Earthquake precursory Observation Network in Beijing, Tianjin and Hebei regions we developed a kind of soft ware for data transmission when there is something wrong with database replication.The main function of the soft ware includes data transmission and display of data and figures.

Key words: Earthquake precursor, Database, SQL Server, Database replication
