What is parallel query processing and how is it useful?
What will be an ideal response?
Since many of today's computers have either multiple processors or multi-core processors, many database management systems have introduced parallel query processing. With parallel query processing, a query can be broken apart and partitions can be run separately on each processor. The partitions have to be defined in advance by the database designer. The advantage to parallel query processing is speed, since the query can be done in much less time in parallel. The query has to be tuned to achieve the best degree of parallelism.
