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.

Customers will be required to provide their credit card details to complete the registration process. The card type, card number, CVV, name on card and the card expiry date will need to be provided. Once these details are verified by the system, the registration process will be completed., The new member will be given a membership ID, which will be a unique number that identifies each member.

Once the customers have become members, they can log in to the system using their username and password. Once the members log in to the system, they can browse the system for books.

When a member finds a book they would like to rent, they should be able to simply click on a rent button. This will allow the members to download the book to their local device. Before the download starts, the system will request the member to confirm the action and provide permission to charge them the cost of the rental. Once the members confirm this, the system charges them using the provided credit card details.

Members can rent up to ten (10) books at a given time. The system is required to record the date rented and expiry date of the book rented. The rental period is for 30 days from the date the book is rented. Once the rental period expires, the book link on the members device will expire. For each book rented, an invoice is sent to the member by email.
