Batch processing is the processing of transactions in a group or batch.
No user interaction is required once batch processing is underway. This differentiates batch processing from transaction processing, which involves processing transactions one at a time and requires user interaction.
Batch processing jobs are usually run on regularly scheduled times but can be run on an as-needed basis at any time, it is particularly suited at end-of-cycle processing (e.g, processing bank's reports at the end of a day or generating monthly payrolls).
One caveat is that the inputs for the processing must be correct or else the results of the whole batch will be faulty, which would cost time and money.
