which includes the total processing cost (sum of all local processing costs incurred at the
participating sites) of the query and the communication cost. The local processing cost
of a distributed query is evaluated in terms of I/O cost (the number of disk accesses)
and CPU cost. The CPU cost is incurred when performing data operations in the main
memory of the participating sites. The I/O cost can be minimized by using effi cient buf-
