DATA PROCESSING SYSTEMS

 The methods of data processing depend upon the following factors:
(a) Volume of data to be processed
(b) Complexity of data processing operations
(c) Computational demands
(d) Processing time constraints and
(e) Economic factors.
Various methods or modes of data processing are given below:
(i). The single user system
(ii). Batch processing
(iii). Multi-programming
(iv). On-line Processing
(v). Real-Time processing
(vi). Time sharing concept
(vii). Distributed processing

The methods of data processing are explained below:

The single user system

It is one-man show and is indicative of one of the earlier stages of computer
development. Here only one person can work at a time. Hence, especially if the machine is
meant for the use of many persons, much computer time is wasted waiting for one person to
finish and debug his program on the machine.
