Theory test answer (all 3)

5:27pm Fri 25th Oct, ANONYMOUS

For the theory test, I was under the assumption that the ERD drawing provided to us would be correct, however, many of the relationship type between entity questions are conflicting. For example: "" Question 2: In the case study, what type of relationship exists between Client and HiredVehicle? a. One-to-One b. One-to-Many c. Many-to-Many d. Recursive Relationship "" The correct answer is listed as b: One-to-Many. However, in the solution provided, the relationship is listed as One-to-One. I do not understand why either the solution provided is wrong, or we are being penalised for using the solution given to us. There are several more questions that follow this concerning logic (Q2, Q7, Q14, Q16, Q21, Q22). Please let me know if I have misunderstood.

I also found this article that confirms that Mehwish told us to refer to the ERD to complete the take-home test.

Even if you follow the ERD the correct answer for Question 2 is b-One to Many. In the ERD it's given as Client(1..1) Hires (0..*)HiredVehicle. So it is One to Many as each client can hire 0 to MANY vehicles and each vehicle can be hired by ONE client only.
