摘要
传统异构数据库存储复制技术只注重数据安全性,忽略了异构数据库存储复制的时效性与可靠性。为此,本文提出一种新的区域网络异构数据库存储复制技术。首先构建区域网络中异构数据库存储框架,通过定向随机游走方法对电力企业灾备中心异构数据进行存储,依据多叉索引树对异构数据库中的数据进行查询处理。然后采用一致性树分布备份技术对本地灾备中心数据进行备份,把待恢复数据分割成若干部分,通过若干差异远程备份服务器实现数据恢复。将所提技术应用于电力企业灾备中心,结果表明,所提技术有很高的存储、复制及备份恢复性能。
Traditional heterogeneous database storage and replication technology only focuses on data security,ignoring the timeliness and reliability of heterogeneous database storage replication. To solve this problem,a new storage replication technology for heterogeneous database in regional network is proposed. First,the heterogeneous database storage framework in the regional network is constructed,and the heterogeneous data of the power enterprise disaster preparedness center is stored by the directional random walk method,and the data in the heterogeneous database are queried and processed on the basis of the multi fork index tree. Then the data of the local disaster center are backed up by the uniform tree distribution backup technology,the data to be recovered is divided into several parts,and the data recovery is realized through several different remote backup servers. The proposed technology is applied to the disaster recovery center of power enterprises. The results show that the proposed technology has high storage,replication and backup recovery performance.
