What is the difference between a batch process and an OLTP?
OLTP: A system whereby each transaction is processed immediately, without the delay of accumulating transactions into a batch. Batch Processing: A system whereby business transactions are accumulated over a period of time and prepared for processing as a single unit or batch. On-line or Real-time vs. Batch Processing: Batch processing permits each day’s work to be accomplished with a cheaper machine. On-line processing reduces to a minimum the time people spend “just waiting around,” but only if the system hardware and software have so much extra capacity that they can meet the peak load, which means that there are many hours of the day hen the system is “loafing.” With priority-based scheduling of the CPU (common in multi-user operating systems) the interactive users will get prompt attention whenever they need it, but the otherwise idle time for the CPU will instead be assigned to completion of the less urgent jobs submitted for batch processing.
