Abstract
A method and system for generating an n-dimensional matrix presentation of at least part of an m-dimensional database including data records and a least one key dimension. Each key dimension includes data value fields. Each data value field has real data therein. A sorting sequence of fact numbers is calculated. The fact numbers are integers that identify the data records. Entry points for each dimension of the n-dimensional matrix presentation are calculated. Each entry point is calculated to be linked with a corresponding fact number of the sorting sequence. A cardinality of the n-dimensional matrix presentation is calculated in dependence on the calculated sorting sequence and the calculated corresponding entry points. The n-dimensional matrix presentation is generated based on the calculated cardinality and the calculated entry points.
