  • Patent number: 6308169
    Abstract: The present invention relates to a method of storing elements in a database and of finding such stored elements. A reference to a storage space intended for the storage of a data element in the database is calculated by means of a mathematical function, wherein the function input data is an external key belonging to the element, and wherein the result obtained with the mathematical function points to an internal position of the element in the database. The result is divided into at least three parts (A, B, C). A first part (A) constitutes a reference to a fragment (A4) belonging to the database, a second part (B) constitutes a reference to a page (B4) within the fragment (A4), and a third part (C) constitutes a reference to a so-called bucket (C4) belonging to the page (B4). A bucket (C4) is comprised of at least one container in which the element can be stored, or is stored.
