· Aggregate Cell an overview ScienceDirect Topics. An aggregate cell aggregates over one or more dimensions, where each aggregated dimension is indied by a ∗ in the cell notation. Suppose we have an n dimensional data cube. Let a = ( a 1,a 2,, a n,measures ) be a cell from one of the cuboids making up the data cube. Chat Online

· Aggregate cells are cells from a nonbase cuboid. Those cells aggregate over one or more dimensions, where those dimensions will be called as "*" in the cell notation. So a cell notation could be (*, d2, d3, ., d9, d10) for example. It is defined that each cell generates 2n – 1 nonempty aggregate cell. As we have got three cells, we ...
