Question 1 The following ER diagram documents entities and relationships that exist in an automobile repair shop: Customer Car Mechanic Job Job Assignment Customers are identified by a unique Cust-No, cars are identified by a unique Vehicle-ID, mechanics are identified by a unique Empl-No, and jobs are identified by a unique Job-Code. A "Job-Assignment" includes a date field that is necessary in case the same mechanic and car get assigned on different trips to the repair shop. It is also possible that a given mechanic might be assigned to the same car on the same day to do more than one job, e.g., do a lubrication and a tune up. Using this ER diagram and the additional information above, create a RSD. Explicitly show the key fields described above and any foreign keys and other required fields. Show non-key and other unimportant fields using the general term "other fields".
