1. Batch Processing.
Batch processing is a technique in which data to be processed or programs to be executed are collected into groups to permit convenient, efficient, and serial processing. It is the simplest form of data processing. With this method, data is entered to the information flow in large volumes, or batches. That is, the processing by computer is performed periodically, at specified time intervals (weekly, monthly, etc) when large volumes are accumulated. Daily transactions in a business establishment, for example, may be batch processed on a weekly basis. Instead of being processed periodically when a sufficient volume has been accumulated.
