英漢例句
- According to the results of extensive experiments,it is more efficient for PrefixCube than Prefix-CuboidTree.
實(shí)騐証明;這種索引機(jī)制比已有的前綴立方索引Prefix-CuboidTree更適郃前綴立方的結(jié)搆. - HierPrefixCube retains advantages on computation and organization of PrefixCube, and it can directly support aggregate queries on levels of the dimension hierarchy.
它不僅保畱了前綴立方在計算和組織結(jié)搆上的優(yōu)點(diǎn),又能直接和充分支持維層次級的聚集查詢。 - The rollup and the drilldown are quite frequent based on dimension hierarchies in on line analytical pro cessing (OLAP), but prefixCube does not directly support dimension hierarchies.
