Abstract
The present disclosure relates to a computer-implemented method for processing a data table. The data table comprises a set of attributes. The method comprises storing the data table on one or more data blocks consisting of one or more sub-blocks. The method comprises determining distinct values of at least one attribute for the one or more sub-blocks relating to a respective data block of the one or more data blocks. The method further comprises storing information indicating the distinct values as hierarchical attribute value information for the respective data block. The hierarchical attribute value information indicates a presence of the distinct values in the one or more sub-blocks.
