The processing of transactions as they occur rather than batching them. Pertaining to an application in which response to input is fast enough to affect subsequent inputs and guide the process and in which records are updated immediately. The lag from input time to output time must be sufficiently small for acceptable timeliness. Timeliness is a function of the total system: missile guidance requires output within a few milliseconds of input, scheduling of steamships requires response time in days. Realtime systems are those with response time of milliseconds, interactive system in seconds and batch system in hours or days.
