Patent ID: 10628452

Abstract:
The invention relates to a method, computer program product and computer system for providing attribute value information for a data extent comprising a set of data entries. For each multidimensional reference point of a set of one or more multidimensional reference points the method comprises: calculating for each multidimensional data entry a reference-point-specific distance between the respective multidimensional data entry and the multidimensional reference point resulting in a set of reference-point-specific distances for the data extent, the respective reference-point-specific distance being calculated using a combination of the attribute values of the multidimensional data entry and a combination of the reference attribute values of the respective multidimensional reference point; determining a minimum reference-point-specific distance and a maximum reference-point-specific distance of the set of reference-point-specific distances; storing for the data extent as attribute value information for further use with query processing the minimum reference-point-specific distance and maximum reference-point-specific distance.
