Easiest form of parallelism to support, particularly in a shared-memory parallel database, because even sequential database systems support concurrent processing.

Speedup can be achieved on batch programs if you rewrite them and split them into parallel streams to take advantage of the multiple CPUs which are now available. Each process is …

Important question: what exactly can we actually parallelize in a parallel database? A chain of operators O_1, O_2, ...,O_k run in parallel, with O_1 working on tuple t_n, O2 on t_(n-1), ...
