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.

 

(a) Outline the pseudocode that the processing must follow when the system sends out the text reminders.

[Marks: 5]

(b) Describe two different methods that the medical centre could use that would allow data to be restored should it be lost for any reason. 

[Marks: 4]

The medical centre is concerned about the privacy of the data it is storing and has to make decisions concerning:

  • access to the data stored on this system
  • storing the data locally or through the use of a cloud service.

(c) Discuss the issues that should be considered before making these decisions.
