Nesting

Nesting is a display technique used to show the results of a multi-dimensional query that returns a sub-cube, i.e., more than a two-dimensional slice or page. The column/row labels will display the extra dimensionality of the output by nesting the labels describing the members of each dimension. For example, the display's columns may be:

January February March
Actual Budget Actual Budget Actual Budget
Prod AProd BProd AProd B Prod AProd BProd AProd B Prod A Prod BProd AProd B


These columns contain three dimensions, nested in the user's preferred arrangement.
Likewise, a report's rows may contain nested dimensions:

Chocolate Bars Unit Sales xxxx xxxx xxxx
 Revenue xxxx xxxx xxxx
 Margin xxxx xxxx xxxx
Fruit Bars Unit Sales xxxx xxxx xxxx
 Revenue xxxx xxxx xxxx
 Margin xxxx xxxx xxxx
