Extracted text: Develop an Context Diagram to model the following description given by the Head of the Centre for Professional Development (CPD) at GTUC: "We make our revenue from training courses. We have courses which we schedule at different locations. Once we have scheduled a course, customers phone in to place bookings for them and we assign instructors to teach the course. Sometimes the person making the bookings is not always the one who will attend the course hence we try to keep track of all the people who are authorized to book places in this way".
