The School transportation was established in 1980. Since then, the School has grown steadily and now has several offices in most of the main cities of country. However, the school is now so large that more and more administrative staffs are being employed to cope with the ever-increasing amount of paperwork. Furthermore, the communication and sharing of information between offices, even in the same city, is poor. The director of the school, John Smith, feels that too many mistakes are being made and that the success of the school will be short-lived if he does not do something to remedy the situation. He knows that a database could help in part to solve the problem and has approached you and your team to help in creating a database application to support the running of the School transportation. The Director has provided the following brief description of how the School transportation operates.

DATA REQUIREMENTS

Each office has a manager (who tends to also be a Senior Instructor), several Senior Instructors, Instructors, and administrative staff. The manager is responsible for the day-to-day running of the office. Clients must first register at an office and this requires that they complete an application form, which records their personal details. Before the first lesson, a client is requested to attend an interview with an instructor to asses the needs of the client and to ensure that the client holds a valid professional driving license. A client is free to ask for a particular instructor or to request that an Instructor be changed at any stage throughout the process of learning to drive. After the interview, the first lesson is booked. A client may request individual lesson for one hour, which begins and ends at the office. A lesson is with particular instructor in a particular car at a given time. Lessons can start as early as 8 am and as late as 8 pm. After each lesson, the instructor records the progress made by the client and notes the mileage used during the lesson. The school has a pool of cars, which are adapted for the purpose of teaching. Each instructor is allocated to a particular car. As well as teaching, the instructors are free to use the cars for personal use. The cars are inspected at regular intervals for faults. Once ready, a client applies for a driving test date. To obtain a full driving license the client must pass both the practical and theoretical parts of the test. It is the responsibility of the instructor to ensure that the client is best prepared for all parts of the test. The instructor is not responsible for testing the client and is not in the car during the test but should be available to drop off and pick up the client before and after the test at the Testing Centre. If a client fails to pass, the instructor must record the reasons for the failure
