Abstract:
Various embodiments are directed to techniques for providing one or more reduced-size rule cubes indicating cell rules. A computer-program product embodied in a machine-readable storage medium includes instructions to cause a computing device to select a cell rule to include in a rule cube based on applicability of the cell rule to a selected portion of a data cube; analyze the cell rule to identify a wildcarded dimension in a specification of cells of the data cube that are subject to the cell rule; and generate the rule cube indicating applicability of the cell rule to the selected portion of the data cube, wherein a cell of the rule cube corresponds to multiple cells of the data cube, and wherein the wildcarded dimension of the rule cube is reduced in length in comparison to a length of the wildcarded dimension of the data cube. Other embodiments are described and claimed.
