batch processing
(1) Performing a particular operation automatically on a group of files all at once rather than manually opening, editing and saving one file at a time. For example, graphics software that converts a selection of images from one format to another would be a batch processing utility. See DeBabelizer.
(2) Processing a group of transactions at one time. Transactions are collected and processed against the master files (master files updated) at the end of the day or some other time period. Contrast with transaction processing.
Batch and Transaction Processing
Information systems typically use both batch and transaction processing methods. For example, in an order processing system, "transaction processing" is the continuous updating of the customer and inventory files as orders are entered. At the end of the day, "batch processing" programs generate picking lists for the warehouse. At the end of some period, invoices and management reports are printed (batch processed).

batch processing [′bach ‚präs·es·iŋ]
| (programming) | batch processing - A system that takes a set (a "batch") of
commands or jobs, executes them and returns the results, all
without human intervention. This contrasts with an
interactive system where the user's commands and the
computer's responses are interleaved during a single run. A batch system typically takes its commands from a disk file (or a set of punched cards or magnetic tape in the old days) and returns the results to a file (or prints them). Often there is a queue of jobs which the system processes as resources become available. Since the advent of the personal computer, the term "batch" has come to mean automating frequently performed tasks that would otherwise be done interactively by storing those commands in a "batch file" or "script". Usually this file is read by some kind of command interpreter but batch processing is sometimes used with GUI-based applications that define script equivalents for menu selections and other mouse actions. Such a recorded sequence of GUI actions is sometimes called a "macro". This may only exist in memory and may not be saved to disk whereas a batch normally implies something stored on disk. |
