Abstract:
Method and system for determining a driving factor for a data value of interest in a multidimensional database, by collecting a context for the data value of interest in the multidimensional database. The data value of interest has dimensional levels with dimensional members outside the drill path of the data value of interest. The dimensional levels are enumerated in a list. A query using the dimensional members of the dimensional level is executed. A variance is calculated for the set of query results. A driving factor for the data value of interest is determined based on the variance. The driving factor is added to the context of the data value of interest.
