Data Processing
Computer data processing is any process that a computer program does to enter data and summaries, analyze or otherwise convert data into usable information. The process may be automated and run on a computer.
It involves recording, analyzing, sorting, summarizing, calculating, disseminating and storing data. Because data are most useful when well-presented and actually informative, data-processing systems are often referred to as information systems.
A data entry is a specialized component or form of an information processing subsystem. Its chief difference is that it tends to perform a dedicated function. A software code compiler (e.g., for Fortran or ALGOL) is an example of a software data processing system.
