PERFORMANCE IMPLICATIONS OF REVERSE CHAINS WITH CHAINED PROGRESSIVE OVERFLOW FILES
The conventional method of loading overflow records in a hash file employing chained progressive overflow requires that the overflow records be loaded as a linked list, with the pointers pointing to the next record of the list. The paper deals with a variation, called reverse chaining, where records...
