摘要
针对 CSCD系统中多个层次、多种类型以及多种应用的数据分布问题 ,以冷冲模协同设计为例 ,提出了分布数据设计的原则和添加副本分配策略 ,特别讨论了利用添加副本分配策略进行数据的冗余分配 .添加副本分配策略对整个应用系统的可用性、可靠性及数据的存取效率有很大的影响 ,提高了
The principle of distributed data design and strategy of adding copy distribution is put forward in order to solve the problem of multi hierarchy, multi type and multi application data distribution in CSCD system by an example of die cooperative design. Specially, the redundancy distribution of data utilizing strategy of adding copy distribution is discussed. The strategy of adding copy distribution has prodigious effect on usability, reliability and data access efficiency of the application system. the reliability and intelligence level are improved.
