What Is Real-Time Data Processing and What Does It Mean? Real-time data processing entails processing data in a short amount of time to provide near-instantaneous results. It requires a constant stream of input data to give a continuous output since the processing is done as the data is supplied. Bank ATMs, traffic control systems, and current computer systems like the PC and mobile devices are excellent examples of real-time data processing systems. A batch data processing system, on the other hand, collects data and then processes it all at once at a later time, resulting in delayed output.
