11. A medical centre uses a computer system to manage both patients’ data and appointments. This system, which is used by the doctors, nurses and secretaries, has two unordered files: a patients’ file and an appointments’ file, both of which can only be accessed sequentially. Every evening the following processing takes place: • a list of appointments for the next day is printed out • reminders are sent by SMS text messages to the patients’ mobile devices.
