摘要
本文主要探讨了分布式数据库中数据分布问题,提出了一种平均代价得益估算模型,然后基于平均代价得益模型给出了一种新的数据分配算法并给予了证明。
This paper mainly discussed data allocation problem in distributed database. It proposed a model based on average cost gaining and then a new data allocation algorithm was proposed which based on average cost gaining, the algorithm was proved in the end.
