The sequence of events in processing information, which includes (1) input, (2) processing, (3) storage and (4) output. The input stage can be further broken down into acquisition, data entry and validation. The output stage can also be further divided into interactive queries and routine reports. A fifth stage is often attributed to this cycle, which is the archiving or deletion of unwanted data. See system development life cycle.
