分布式数据库系统中同步数据复制研究

The Research of Eager Replication in Distributed Databases

数据复制是分布式数据库常用的一种方法,以提高数据的可用性和系统的性能,主要从理论上分析了同步复制的一些特点,说明了同步复制算法的实用性。同时利用数据复制有效的降低了死锁的频率。

The methods of Data replication are widely adopted in distributed databases to improve data availability and system performance. In this paper, Some characters of the eager replication were analysed in theory, and as a result we can find its practicability.
