Background 

Scenario – Home Bookstore: Rental Process 

Samuel Gabriel is an entrepreneur who has decided to launch his own online bookstore called ‘Home Bookstore’. He has been working with his in-house IT team on the process of developing the Home Bookstore system. You have been brought in by Samuel as an independent IT consultant to assist with the design of the system. Samuel has sent you some correspondence outlining the constraints that the system should work within. An extract of this correspondence is below: 

Extract of note from Samuel 

The company intends to keep track of the book stock by assigning each book a number that will uniquely identify it. Apart from this, the book title, book type, genre, file size, year of release, synopsis, and the rental price of the book are also expected to be recorded in the new system. 

The customers that expect to rent books from ‘Home Bookstore’, will be first required to register themselves with the store to become members. They will be able to do this easily by providing their personal details such as their first name, last name, email address, telephone number, address and date of birth. They will also be required to pick a username and a password for login purposes. The username will need to be an email address. The password will need to consist of eight characters that include an upper-case letter, lowercase letters, at least one number and one symbol.
