Create a DFD (Context and Level 0) for a Car Servicing Center.

Model the login process for walk-in customers. These customers can be new or

existing. All new customers must be first registered. Each customer may own

multiple vehicles, and all vehicles need to be assigned to a Mechanic based on

schedule and availability. Each vehicle may have one or more service requests. Some

services might require ordering of parts from a supplier. Post servicing, the

customers will make payments, as needed. All service requests are stored such that

Management can review periodic reports for performance evaluation.
