What is the difference between batch processing and online processing in a mainframe system?

Batch Processing vs Online Processing in Mainframe System

Batch processing and online processing are two primary methods used in mainframe systems for handling data and processing tasks. Here is the difference between the two:

Batch Processing:

Batch processing is a method where data is collected, processed, and output in a group or batch. In a mainframe system, batch processing involves running jobs at a scheduled time, usually during off-peak hours. This method is suited for handling large volumes of data that do not require immediate processing.

Online Processing:

Online processing, also known as real-time processing, involves handling data and transactions immediately as they occur. In a mainframe system, online processing allows users to interact with the system in real-time, enabling quick responses to input or requests. This method is ideal for applications that require immediate processing and real-time access to data.

In summary, batch processing is used for processing data in bulk at scheduled times, while online processing is used for real-time interaction and immediate processing of data in a mainframe system.
