【摘要】 简要介绍了地震前兆数据的现状及其实现数据共享的必要性 ;分析了常用的二种通用Web数据库的体系结构及应用技术 ,它们是基于通用网关接口 CGI的体系结构和基于服务器扩展 API的体系结构。考虑到前兆台网中心硬件设备的条件、所运行的数据库平台和地震前兆数据的复杂性和多样性特点 ,前兆数据在 Internet上的共享服务采用基于通用网关接口 CGI的体系结构编写应用程序来实现。以 WWW服务器为平台 ,通过 Web服务器方式在浏览器上实现共享 ,可检索任意台站、任意观测方法、任意地点、任意时段的前兆数据 ,实现地震前兆数据信息网络服务功能。更多还原

【Abstract】 This paper briefly describes the status of seismic precursory data restored in Center for the Earthquake Precursory Observation Network of China (CEPONG), Center for Analysis and Prediction, CSB and the necessity of realizing data share through Internet. The authors analyzed in detail the system structure and its technique of two common general Web database named the system structure on the basis of CGI and the one on the basis of API. By considering hardware condition of CEPONC, the database platform used and the complexity and variety characteristics of seismic precursory data, we use the system structure of CGI to compile application program and then realize precursory data share through Internet. Specifically, we use WWW Server and Web Sever as application running environment through Browser such as Internet Explorer (IE) and Netscape to realize seismic precursory data sharing service. The search for precursory data of arbitrary stations, various observational methods, different times and locations is provided, and the information network service function for seismic precursory data is realized.更多还原
