Abstract

System and method to compress data records by providing data records with a binary structure; dividing the data records into several bit vectors; reducing the size of each bit vector by dividing the bit vector into consecutive partial areas of equal size, each partial area consisting of n bits, classifying the partial areas as trivial partial areas, quasi-trivial partial areas and non-trivial partial areas, combining one non-trivial or several consecutive non-trivial partial areas into one so named R block, and removing the trivial partial areas; as well as combining one quasi-trivial or several consecutive quasi-trivial partial areas into one so named O block.
