Question 22. (13 marks) Marks

Refer to the following information when answering all parts of Question 22.

Wyegow Council employs parking wardens to patrol the streets, find cars that are parked illegally and issue traffic infringement notices.

When the wardens find an illegally parked car they take three digital photographs. The first photograph is a close-up of the car’s license plate, the second is a close-up of the parking sign that has been infringed and the third is of the car with the parking sign. All photos are date stamped.

On return to their office the wardens manually upload the photos for storage and locate the details of the owner of the car in the RTA database. They record the owner's name, address, registration number, date and place issued into a database and perform a mail merge to create an infringement notice.

The photos must be kept in case the car’s owner challenges the details in court, when they will be produced as evidence. Currently they are printed and stored in a filing cabinet labelled with the car’s registration number.

The council is considering developing an automated system that will store the infringement details and photos in an electronic database, using the new Licence Plate Recognition (LPR) technology. This system is currently used by police to detect stolen vehicles, to monitor parking and to automatically retrieve the owner’s details from the RTA database and generate infringement notices.

(a) Construct a context diagram for the current Wyegow Council parking warden system.
