INSTRUCTION 1. Create a Crow's Foot ER diagram for each of the following business rules. The diagrams should clearly describe and identify each entity and show relationships. Show all cardinality, primary keys, and foreign keys. Use verbs to clarify your relationships. Show only the attributes that are contained explicitly in the case/ business rules. 2. You should also make and document any reasonable assumptions where you feel the case is vague, ambiguous, or missing any data necessary to meet the requirements. 3. Simplify MEN relationships, if any. 4. You may develop the diagram on paper and submit the scanned version or you may use any relevant software. If you use a software, make sure that the file you submit is openable in the windows environment. If you can, please submit a PDF file. Steps to do: The requirements collection and analysis phase of the database design process has provided the following data requirements for a company called Convenient Rentals, which rents out vehicles (cars and vans). a) The Convenient Rentals has various outlets (garage/offices) throughout the Niagara Region. Each outlet has a number, address, phone number, fax number, and a manager who supervises the operation of the garage and offices at each site. A manager is an employee as well. (3 Marks)b) Information is stored on the staff based at various outlets including staff number, name (first and last name), home address, home phone number, date of birth (DOB), sex, Social Insurance Number (SIN), date joined the Company, job title, and salary. Each staff member is associated with a single outlet but may be moved to an alternative outlet as required, although only the current location for each member of staff is stored. (3 Marks) () The Company retains data on dependants for those staff members who have dependents. The data stored on dependents includes dependent ID, name of the dependent, relationship to the staff, sex, and date of birth. (2 Marks) d) Each site is allocated a stock of vehicles for hire, however, individual vehicles may be moved between outlets, as required. Only the current location for each vehicle is stored. The registration number uniquely identifies each vehicle for hire and is used when hiring a vehicle to a client.
