Exercise 1 (total 12pts ): Consider the following application development request. The management of a high-school desires to commission you startup to develop a Web software application that can be used to manage the reservations of classrooms for classes, as well as the reservations for the needed teaching equipment (laptops, video projectors, ...etc.). A course may have many classes but has one coordinator (who teaches one class). A teacher makes a reservation for a classroom and/or the equipment he/she needs after checking their availability. Some equipment needs to be rented by the coordinator from a company specializing in school supply rentals, through a rental system. The rental can only be confirmed after an approval given by the school administration. The administration clerk may decide to transform a rental request of into a purchasing request if the rental period is deemed too long or the equipment is requested frequently. The purchasing request needs to be approved by the principle, however. The schedule of the classrooms can be consulted by everyone (teachers and students). On the other hand, the hourly summary of classes, for each given teacher, is calculated from the classroom schedule, and can only be consulted by the specific teachers. Finally, the course coordinator who can edit the hourly summary for the course. P.S. Make any assumptions you see fit, but explain you assumptions. 1. (3 pt) Give a high-level diagram for the application. 2. (3 pt) Give a second-level detailed diagram showing the decomposed use-cases. 3. (3 pt) Give a detailed description for the use-case "Rent Equipment". 4. (3 pt) Give a sketch for the "Rent Equipment" screen
