移动通信数据备份查询的一种新方法

移动通信数据的海量增加,对以前数据的查询显得束手无策.现在普遍采用的是把以前的数据整体备份到磁带或光盘上,文中提出一套切实可行的数据备份和整理方案,基于应用程序和过程、触发器机制把原始数据库数据转换到备份查询数据库中,既保证了数据库系统的运行性能,又不损失系统的历史数据,同时起到数据备份功能,在完整备份并删除相应旧的数据的基础上,又能对以前的数据进行查询和统计,延长数据的实际存活时间.

A New Method of Data Backup and Locating on Mobile Communication

Because of the vast data increments on mobile communication,it makes people inability to locate data. Now it adopts the method of copying old data to tapes and disks as a whole.
