A database system and method for organizing data elements according to a Hilbert curve, said data elements being representable by a plurality of coordinates, said database system comprising:first means for generating a plurality of bitblocks by bitwise interleaving the coordinates of the data elements;second means for applying a fliprot transformation to a first bitblock;said fliprot transformation comprising a flip transformation and a rot transformation, said flip transformation inverting bits of said bitblock, said rot transformation interchanging bits of said bitblock;third means for obtaining, for each further bitblock, a fliprot transformation by a concatenation of two or more fliprot transformations; andfourth means for applying fliprot transformations to their corresponding bitblock;whereby the bitblock bits determine the organization of said data elements according to said Hilbert curve.
