ABSTRACT:
Systems and methods are provided for inserting a new node into a tree structure for use within a database system, wherein the tree structure comprises one or more parent nodes having space there under, and one or more child nodes; wherein each node comprises an identification, a left value, a right value, a width, and a tree node interval; each child node comprises of a pointer to the associated parent node of the child node; and the new node is a child node having an identification corresponding to the identification of a parent node. The method may comprise determining the identification of the parent node of the new node, determining the width of the new node, determining whether a gap exists in the tree structure for a parent node having an identification equal to the determined parent node identification, and if a gap exists, inserting the new node into the gap if the width of the gap is equal to or greater than the width of the new node.
