Example Sentences:

	1.	Efficient incremental maintenance for distributive and non - distributive aggregate functions cui - ping li and shan wang 有效的针对分布型和非分布型聚集函数的增量维护
	2.	Conference on very large data bases vldb 00 , cairo , egypt , 2000 , pp . 461 - 472 . 10 lakshmanan l v s , pei j , han j w . quotient cube : how to summarize the semantics of a data cube 本文针对可分布型聚集函数如sum ，提出了两种有效的增量维护方法，一种是单元组递增更新的方法，另外一种批量更新的方法。
	3.	Such an approach not only is useful for distributive aggregate functions such as sum but also can be applied to the maintenance of holistic aggregate functions like median which will require the storage of a set of tuples for each equivalence class 该方法不仅对分布型聚集函数如sum非常有效，而且也可以应用于非分步型聚集函数如median的增量维护。这样的聚集函数需要存储所有的基元组。
	4.	Incremental maintenance of quotient cube for sum and median . technical report 02 - 1 , school of computing , nus , dec . 2 , 2002 , pp . 1 - 18 . 18 wang w , feng j l , lu h j , yu j x . condensed cube : an effective approach to reducing data cube size 针对非分布型聚集函数如median ，提出了一种有效的滑动窗口技术，该技术和addset存储结构的结合极大地减少了维护不可自维护型函数时所需要的存储空间和运行时间。
	5.	Unfortunately , as changes are made to the data sources , maintaining the quotient cube is non - trivial since the partitioning of the cube cells must also be updated . in this paper , the authors design incremental algorithms to update a quotient cube efficiently for both sum and median aggregate functions 然而，当数据源发生改变的时候， quotient数据立方体很难进行维护，尤其是针对median这样的非分步型聚集函数，因为当插入新的元组时， quotient数据立方体中的等价类有的需要进行拆分，有的还需要重新生成。
