2 © UCLES 2008 9713/03/O/N/08 Scenario 1 Questions 1 and 2 A company called ROCK-ICT sells rock music concert tickets via an Internet booking system only. Tickets aren’t posted out as customers print out their own tickets. However, it is possible for customers to sell the concert tickets on auction sites. ROCK-ICT are concerned about this and have decided that customers must enter their personal details when booking their tickets. These details will be stored in a database by ROCK-ICT. They are aware that security is an issue due to the nature of the stored information. To ensure that the details of the concerts are correct, ROCK-ICT is in regular contact with all its stars using video conferencing. Scenario 2 Questions 3, 4, 5, 6 and 7 South India Airlines is a company making regular flights throughout Asia. They employ a number of pilots who require regular simulator training. The airline uses the services of Indiamet, who provide local and national weather forecasts. Indiamet have monitored weather conditions over a number of years. All the information is now stored on its large computer system. South India Airlines is encouraging travel agents to use online booking as it increases company efficiency. The Dhesi travel agency presently uses a manual paper-based system to book flights and holidays. A systems analyst has been brought in to produce an improved computerised system for them. The staff at Dhesi’s travel agency could now be prone to health and safety issues once the new computerised system is operational. South India Airlines require their passengers to produce their passports or ID cards when checking in. The number on the bottom of the back page of a passport is read by a suitable scanning device linking directly to a Government database.

UNIVERSITY OF CAMBRIDGE INTERNATIONAL EXAMINATIONS GCE Advanced Subsidiary Level and GCE Advanced Level MARK SCHEME for the October/November 2008 question paper 9713 APPLIED ICT 9713/03 Paper 3 (Written B), maximum raw mark 80 This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners’ meeting before marking began. All Examiners are instructed that alternative correct answers and unexpected approaches in candidates’ scripts must be given marks that fairly reflect the relevant knowledge and skills demonstrated. Mark schemes must be read in conjunction with the question papers and the report on the examination. • CIE will not enter into discussions or correspondence in connection with these mark schemes. CIE is publishing the mark schemes for the October/November 2008 question papers for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level syllabuses and some Ordinary Level syllabuses.
