Problem 1. Design a database for UM Blue Bus system. You need to include the following information: Bus Drivers: Driver Name, Age, Gender, Email, Employment Type (part-time, fulltime, student, etc.), Salary. Buses: License Plate, Vehicle Type, Model Year Stops Information: Stop Name, Location Route Information: Route Name, Number of Stops Shift Information: Route, Bus, Driver, Day, Start Time, End Time Also, take into account that a Stop can be used by multiple routes and a route can have multiple stops, so you may need to have an additional table to show this relationship You can create primary keys when necessary (e.g. DriverID. BusID, etc.). Identify the primary keys. Draw an ERD of this database. Show the relationships in your ERD
