Abstract:
A method for storing data-information within a computer data-base, comprising the steps of: structuring the data-information in a node hierarchy which is comprised of a tree-structure that includes a root-node, one or more levels of intermediate nodes, and one or more leaf-nodes, wherein the root-node includes one or more root-elements, respective intermediate nodes include one or more intermediate elements, and respective leaf-nodes include one or more leaf-elements; linking a first intermediate element within an intermediate node to the root-element or to an intermediate element within an intermediate node placed at a higher level in the hierarchy, and wherein remaining intermediate elements within the intermediate node are linked to said first intermediate element, wherein a first leaf-element within respective leaf-nodes is linked either to the root-element or to an intermediate element of one of the intermediate nodes and remaining leaf-elements in a leaf-nodes are linked to the first leaf-element, wherein respective elements include address-information for the links and the data-information; ordering the elements within a node in a logical order with respect to the data-information, and where the data-information in respective elements constitutes the difference in data-information in relation to the data-information belonging to preceding element in the hierarchy, wherein the data information within said root-element constitutes a start value; in that said start-value is comprised of the actual data-information; in that differential information within remaining elements is comprised of a data-word that represents the actual difference of the data-information in relation to the data-information that belongs to the preceding element, regardless of where the difference lies within said data information.
