Data processing is any process that a computer program does to enter data and summarise, analyses or otherwise convert data into usable information. Because data are most useful when well-presented and actually informative, data-processing systems are often referred to as information systems. Data-processing systems typically manipulate raw data into information.
Data processing may or may not be distinguished from data conversion, when the process is merely to convert data to another format, and does not involve any data manipulation.
