data processing

Use of computers for performing clerical tasks such as stock control, payroll, and dealing with orders. DP systems are typically batch systems, running on mainframe computers.

Data processing cycle

For data to be processed the following cycle of operations must be undergone: data are collected, then input into a computer where they are processed to produce the output. As the output may also be the input of a subsequent process the process is deemed cyclical. While being processed, data may undergo other operations such as storage and validation.

A large organization usually has a special department to support its DP activities, which might include the writing and maintenance of software (programs), control and operation of the computers, and an analysis of the organization's information requirements. See also computer personnel.

The term ‘data processing’ has now been superseded by ‘information technology’ (IT).
