Answer to Question 1

A requirement is something the database must do to meet its business purpose. For instance, a retail sale database must track the date and time of every sale, the items sold and the prices charged. A business rule is a rule about how data is acquired and processed. An example could be that a customer is required to give their information before a sale can be completed or perhaps, that a customer is encouraged to give their information before a sale, but that the sale can proceed even if they don't wish to.

Answer to Question 2

FALSE
