    Project I
    Database System for a car rental company
    Consider the company requirements as follows:
    A car rental company needs a comprehensive database system to streamline its operations. The system should enable customers to rent cars from multiple locations (Riyadh, Jeddah, Makkah, Dammam, Al-Khobar, Qasim, Tabuk, AL-Baha, Al-Jawf, Ha’il, Aseer, Jazan, Najran). Customers will be required to register by providing their full name, email, phone number, and date of birth. The company owns a fleet of cars, which contains important details such as the manufacturer, model, manufacturing year, license plate, and daily rental rate. Every rental transaction will involve the customer, the rented car, and the rental period (start and end dates). As the company operates in multiple cities and states, multiple rental locations are available, each with its name, street address, city, state, and postal code.
    Customers can rent multiple cars, and each car can be rented by multiple customers. A specific rental location will be associated with each car. Moreover, each rental transaction will be linked to a specific rental location. To maintain data integrity, constraints such as unique customer and car IDs will be enforced. Rental transactions must be associated with both a customer and a car.
    On the other hand, each car should be linked to a rental location. Reports on rental transactions will be generated, including customer information, location, and period. User roles will be implemented for customers and system administrators. Customers will be able to view available cars, rent cars, and access their rental history. Meanwhile, administrators will be able to manage car inventory, rental locations, and customer accounts.
    The system will ensure that cars are available for rent at specific locations and track car availability to prevent overbooking. Rental costs will be calculated based on the rental rate per day. User authentication and authorization will be implemented to protect customer data and system operations.
