airline is real time processing...this is bcz in real time the input, process and output are carried quickly enough to influence or control the source of the input data.(airline booking system affects worldwide)
Patient readings in ICU uses online processing(it does not affect worldwide)......It allows a computer device to be under the immediate control of the main computer.
This is the difference between online and real time processing.
this is what our teacher said about real time and online processing...
