BATCH PROCESSING
Batch processing is the execution of a series of programs ("jobs") on a computer without manual intervention.
Jobs
are set up so they can be run to completion without human interaction. All
input parameters are predefined through scripts, command-line arguments, control files, 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. This operating environment is termed as "batch
processing" because the input data are collected into batches or sets of records and each batch is
processed as a unit. The output is another batch that can be reused for computation.
