In this project, you will design and implement a database for keeping track of information about a car rental company. You will first design an EER schema diagram for this database application. Then, you will map the EER schema into a relational database schema and implement it on MYSQL. Finally, you will load some data into your database, and create some queries and update transactions. Assume that the following requirements were collected for this application: 1. The database keeps track of CUSTOMERS. Each CUSTOMER has a unique IdNo (assume this is a unique integer generated by the system for each new CUSTOMER, such as 1, 2, 3, ...), a Name (assume this is string consisting of an single initial and last name only for simplicity, such as "J.Smith" or "R.Wong"), and a Phone (a string of 12 characters such as "817-272-3000"). 2. The database keeps track of CARS available for rental, which are categorized based on their type. There are six main types: COMPACT, MEDIUM, LARGE, SUV (Sports Utility Vehice), TRUCK, and VAN. Each type of car has its own DailyRate and WeeklyRate (assume all cars of the same type have the same rental rates). For simplicity, we will assume that there is only one rental location. 3. Each CAR has a VehiclelD (a unique number for each car - assume it is a number 1001, 1002, 1003, ...), Model (Chevy, Toyota, Ford, ..), and Year (2015, 2014, ...). 4. The database will keep track of the current (active) RENTALS as well as scheduled RENTALS of each CAR. The are two types of RENTAL: DAILY and NEEKLY. For each DAILY RENTAL, the information kept will include the specific CAR and CUSTOMER as well as the NoOfDays, StartDate, and ReturnDate (the ReturnDate can be calculated from the StartDate and NoOfDays). For each WEEKLY RENTAL, the information kept will include the specific CAR and CUSTOMER as well as the NoOfWeeks, StartDate, and ReturnDate (the ReturnDate can be calculated from the StartDate and NoOfWeeks). Each rental will also have the AmountDue for the rental, which is a derived value that can be calculated from the other information. 5. The database will also keep track of which CARS are available for rental during which periods. Part 1 You will first design an EER schema diagram based upon the RENTALS database requirements specified above, and create an EER schema diagram and documentation report describing your design choices. As part of this assignment, you should identify any missing or incomplete requirements, and explicitly state them in your documentation. You should also explicitly state any assumptions you made that were not part of the requirements listed above.
