基于Oracle复制和分区技术的分布式网通销售系统的研究与设计

Research and design on Oracle replication and partition technologies based on distributed system of netcom communication company

四川网通数据库具有数据量庞大、分布式管理的特点。为了实现双层管理,构建分布式数据库系统具有重要意义。复制技术能解决数据之间数据同步问题,orac le分区表技术能够区分数据源,保证数据安全的同时,提高数据处理效率。本文基于orac le9 i的复制和分区管理技术对分布式销售系统数据库做了改造,并用实例论证了其效率和可性行。

The databases in SiChuan netcom communication company are having large data and are managed with distributed policy. In order to manage the two layer structure easily, it is important to build distribution databases. Replication technology can keep databases synchronization and partitiion technology not only can seperate datasource to save data, but it also improves databases efficiency. This article is about what have been reconstructed based on oracle replication and partition technologies. Also some instances have been showed to test its efficiency.
