| 摘 要： | 为解决分析预报等相关专业软件访问前兆数据库时存在的性能与安全问题，本文设计了地震前兆数据库系统共享接口软件。该软件可以隔离数据库与应用程序，对应用程序的数据使用情况进行审计与控制，切断非法、低效的数据访问请求；同时，使用连接池、数据缓存和数据压缩等技术提高前兆数据的访问速度。软件无需安装Oracle客户端，易于使用，屏蔽了数据库表结构的复杂性。

| Abstract: | Earthquake precursor data exchange interface is developed in order to solve problems caused by direct connection to earthquake precursor database, which can isolate database and application software, and has ability to monitor and control data usage and block illegal and low efficient data request. The interface software combines connection pool, data cache and data compression technology that can gain very high data transfer speed. The interface software is also easy to deploy without the need to install Oracle client, and easy to use without the knowledge to table structure of precursor database. |
