The query processing in the distributed database systems is comprehensively summarized. This paper shows that using HASHINGmethod for thereduction of semi-join communication cost is beneficial.
In addition, a general expansion of lip ear hashing and the results of simulation of performance of the method are given as well.
此外，本文还对线性散列技术作了一般性扩充，并通过模拟实验研究了方法的性能。
