Scenario 2

Questions 3 and 4

Some teachers at the Nairobi International School use computers to store records of their students including examination results. The Headteacher Peter Onyango has decided that all teachers will use computers to keep their assessment records and that this information will be stored centrally.

In order to introduce this new system Peter has asked Mary, a systems analyst, to analyse the existing paper based system that a number of teachers are still using.

Each student has a unique ten digit student number.

After the analysis phase Mary will design the new system. Part of this process will be the design of validation checks. Mary will use presence checks and existency checks on the student number and presence checks on the examination scores, which are marks out of 100. In addition, Mary will need to decide on other validation checks.
