draw a level 0 diagram as well as a context diagram for the following scenario
When renting a car from Banz Car Rental Agency, persons renting a car from the agency will be given a brochure of the type of vehicle, insurance on vehicle and the rental conditions of the vehicle, vehicle class etc. customers would then need to provide their private information such as their names, addresses, telephone number, credit card etc. the customer then chooses they type of vehicle he wants and the agency will check to see if that car is available for the customer. If that vehicle is available then the customer would then sign the necessary documents which he would receive from the agency. After this has been completed the vehicle would be classed as being rented and a new rental record is added to the agency’s file if the customer is new or a file drawn to be updated if the customer is an existing customer. The date out of the vehicle would be tabulated by the business and the date returned left empty (when the vehicle would be returned the agency would update their files by filling in the date returned field). The agency would then bill the customer and the bill paid by the customer
