Information about Batch Processing
Batch processing is execution of a series of programs ("jobs") on a computer without human interaction.
Batch jobs are set up so they can be run to completion without human interaction, so all input data is preselected through scripts or commandline parameters. This is in contrast to interactive programs which prompt the user for such input.
Batch processing has these benefits:
Batch processing has grown beyond its mainframe origins, and is now frequently used in UNIX environments, where the cron and at facilities allow for scheduling of complex job scripts. Similarly, Microsoft DOS and Windows systems refer to their command-scripting language as batch files and Windows has a job scheduler.
A popular computerized batch processing procedure is printing. This normally involves the operator selecting the documents they need printed and indicating to the batch printing software when and where they should be output. Batch processing is also used for efficient bulk database updates and automated transaction processing, as contrasted to interactive online transaction processing (OLTP) applications.
Scripting languages (commonly called script languages) are computer programming languages that are typically interpreted and can be typed directly from a keyboard.

Batch jobs are set up so they can be run to completion without human interaction, so all input data is preselected through scripts or commandline parameters. This is in contrast to interactive programs which prompt the user for such input.
Batch processing has these benefits:
- It allows sharing of computer resources among many users,
- It shifts the time of job processing to when the computing resources are less busy,
- It avoids idling the computing resources with minute-by-minute human interaction and supervision,
- By keeping high overall rate of utilization, it better amortizes the cost of a computer, especially an expensive one.
