Online processing system vs batch processing system Now with the passage of time latest computer devices do work of both batch processing and online processing at a time. In decent development now our mobiles and small devices also do some type of batch processing. As online processing involve mobiles data also so it is expensive. Batch processing work in batches and then jobs is divided into sub jobs and then processed so it don’t need lot of hardware resources. If we compare with batch processing system than online systems are expensive. The ACT Batch job deployment process has been standardized across ACT.Online processing is very effective these days. The ACT Batch job structure process has been standardized across ACT. The ACT Batch Environments support the development, QA, and production environments for all batch processes and jobs. It allows the system to use different priorities for batch and interactive work.

By keeping high overall rate of utilization, it amortizes the computer, especially an expensive one.

It avoids idling the computing resources with minute-by-minute manual intervention and supervision.

It can shift the time of job processing to when the computing resources are less busy.

This operating environment is termed as "batch processing" because the input data are collected into batches of files or tasks and are processed in batches by the program. A program takes a set of data files as input, processes the data, and produces a set of output data files.

This is in contrast to "online" or interactive programs which prompt the user for such input. So, all input data are preselected through scripts or command-line parameters and scheduled or triggered via specific dates or completion of other actions. Jobs are set up so they can be run to completion without manual intervention. Batch processing is execution of a series of programs ("jobs") on a computer without manual intervention.
