1. A method for processing a multidimensional query, comprising: in response to determining that a multidimensional expression includes an operator with multiple operands; finding, using a processor of a computer, a non-degenerated set of an evaluation result of the operation as a minimum combination that contains non-degenerated sets of the multiple operands for the operation; evaluating the multidimensional expression by iterating through values of evaluation results of the multiple operands to find value pairs used to calculate the operation and to generate a representation that includes an evaluation context, a degeneration status, and a condensed value storage that does not store data that would be replicated due to degeneration; and storing the representation.
