used for decades in approximating query result sizes in the query optimizer, and methods such as the Equi-Width and Equi-Depth histograms have been incorporated in all real-life systems. This is because histograms are simple structures, and can be easily utilized in determining efficient Query Evaluexhilaration 发表于 2025-3-22 02:09:52
