Without knowing it, they are asking if they can parallelize their divisions' IT operations. As DBAs, when faced with a large, time-consuming data import, we instinctively ask, "Can we break up the import by users, and then run them all at the same time?" We are trying to parallelize! And Oracle gets involved as well. It has multiple background processes running in parallel, Oracle parallel query, Oracle Parallel Server (excuse me, I meant to write Real Application Clusters), and distributed queries.
