ABSTRACT:
A computer-based method and system of processing records read respectively from first and second related tables of a database includes determining whether data contained in the records read from the first or second tables is unevenly distributed. Records corresponding to evenly distributed data are searched for matches using a first set of instances of the hash-join operator, and records corresponding to data which is unevenly distributed are searched for matches using a second set of instances of a hash-join operator.
