摘要:
本文在分析了原有的几种估计关系运算结果大小的方法的基础上,提出了一新的估计模型——UDB,并对其建造方法、使用方法、适用情况及估计精度做了较详细的讨论。
Abstract:
A new model——UDB is developed for the size estimation of the relations resulting from relational operations. Following a review of some previous methods, the method of construction and usage of UDB model as well as its suitabilty and estimation precision are discussed.
