Batch processing is execution of a series of programs on a computer without manual intervention. Jobs are set up so they can be run to completion without manual intervention. So, all input data are preselected through scripts, command-line parameters, or job control language. This is in contrast to “online” or interactive programs which prompt the user for such input. A program takes a set of data files as input, processes the data, and produces a set of output data files.
