Please develop an E-R diagram to illustrate the following situation: If you need to make assumptions, please state them. There is no need to model possible supertype/subtype relationships. At a car dealership, the service department deals with a large number of vehicles every day. One of the key tasks of the service consultants is to meet with every customer who brings a vehicle to be serviced and find out why a vehicle is brought to the shop and what specific problems might need to be addressed. The dealership prides itself for its personal attention to its customers and the detailed information it maintains about each vehicle. During the conversation with a customer bringing the car to service, a service consultant will use the information they have available about the customer and the vehicle to increase the level of trust between the customer and the dealership and to make suggestions regarding possible additional preventive maintenance services that might be useful for the customer (and profitable for the dealership). It is essential that the interaction between the customer and the service consultant is supported as well as possible. During that communication, the service consultant has to identify the vehicle, the customer, specific predefined service tasks or collections of tasks (such as a 30,000-mile service), and problems that have to be explored further. The main questions the customers typically have when they bring a vehicle to the service are the time it will take for them to get their vehicle back and the estimated cost. At the end of the initial conversation, the vehicle is assigned to a service technician, whose task it will be to complete the repair work, record the number of hours of labor and the parts consumed, and complete the repair work documentation at the end of the process.
