Follow the process below to help you do this: Consider a model of an airport with planes, models of planes, test of planes, and technicians. Draw an ER diagram to represent these entities and their attributes. Planes have a unique registration number. Airplane Models are each identified by a model number (e.g., DC-80, A380, B747), and each have a capacity and a weight. Several technicians work at the airport. You need to store for each technician the name, phone number, address, and salary. The airport has a number of tests that are used regularly to ensure that airplanes are safe.
