摘　　要：前兆数据库是前兆台网的核心,它储存汇集了台站的监测数据,由于近年来前兆台网仪器不断增加,数据不断增多,数据库存储空间开始变小,这样将导致台站数据交换缓慢,甚至入不了库,造成数据缺失,所以维护数据库显得极为必要。The precursor database is the core of precursory network, which stores monitoring data collected at seismic stations. Due to the increased precursor network instruments, more and more data has been collected, and database storage space has become less. This will lead to data exchanging slowly, and even can＇ t be stored into the library and missing data. Therefore the maintenance of the database is quite necessary.

关 键 词：前兆数据库 存储空间 维护数据库
