Draw the Data-flow diagram for the following project:

the purpose of this project is the automation of a parking lot. the system has to control the incoming reservations and parking spots.when a reservation comes in,if the customers plate number is confirmed to be legal by the Database, the system will search for a free parking spot and reserve it for the customer and subtract the appropriate amount from the customers account credit. the system is controlled by an admin, the admin can login to the system,add customers,remove customers,edit customer profiles, create and cancel reservations, control the closure of part of the parking or all of it. each customer with a profile in the system can login to it and request for a reservation(by giving the needed info e.g. what time,how long etc) and add to his/her account credit. when the customer wants to leave the parking and is going to log out from the system,if he/she has had any delay,the system computes the penalty and subtracts it from the customers account credit and updates the parking spot the customers car was on to being available.
