摘　　要：受到冗余数据影响,导致数据库缓存效果较差,对此,提出基于空间数据维度划分的层次化通信网络备份数据库缓存子系统设计。考虑响应实时交易请求,优化分布式缓存数据库,实现数据同步备份。在硬盘的不同位置设计单片机的冗余阵列,使硬盘驱动器均衡重叠;采用条带和镜像相结合的方式,使RAID0+1磁盘阵列具有快速读写能力;通过缓存控制模块驱动数据缓存区的一致性维护,根据数据在空间维度上的分布情况,确定数据集对应的维度投影,消除网络冗余数据,完成层次化通信网络备份数据库缓存子系统设计。由实验结果可知,该系统不会受到冗余数据影响,具有高于85%的缓存效果。Due to the influence of redundant data,the effect of database buffer memory is poor,usually.In view of this,a design of hierarchical communication network backup database′s buffer memory subsystem based on spatial data dimension division is proposed.The response to real-time transaction request is taken into account,and the distributed buffer memory database is optimized,so as to realize data synchronous backup.The redundant array of SCM is designed in different positions of the hard disk to make the hard disk drive evenly overlapped.The combination of strip and mirror image is taken as a way to make the RAID0+1 disk array have fast read-write ability.The buffer memory control module is used to drive the consistency maintenance of the data cache region.The dimension projection corresponding to the data set is determined according to the data distribution in special dimension,so as to eliminate the network redundant data and thereby complete the design of the buffer memory subsystem of hierarchical communication network backup database.The experimental results show that the proposed system will not be affected by the redundant data and its buffer memory effect can reach 85%.
