ABSTRACT:
A database contains listing records, and index records each providing a pointer to a listing record. The index records are stored, in a predetermined order, together with distributed free space to allow the future insertion of new index records. Each index record is provided with a radix sort key associated with a primary keyword in the corresponding listing record whereby that index record may be inserted in the correct order without reference to the listing record.
