BookWorld - Online Book Ordering System
Create an online form that will record customer orders for an online book-ordering business. The customers will simply log on to this online form, create an account, and click submit. The information collected consists of the customer's first and last name, residential address, city, zip code, mobile number, and email address. After entering all the information, a unique identification number is created for each customer.
The customer will then choose the books from the website, pay by credit card, and click Submit. Their orders will then be processed, and a postal delivery will be organized by the business to deliver the order to the customer. The delivery will be made via "Australia post". The minimum order is $20 and free delivery within the SYDNEY Metro area. A $10 delivery fee will be charged for addresses outside the SYDNEY Metro zone. The business will do the delivery all over Australia for the flat delivery fee of $10. And customers who's purchasing the books for more than $100 will get free delivery.
