Case Study BookWorld – Online Book Ordering System You were asked to 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 organised 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 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 the customers who’s purchasing the books for more than $100 will get free delivery. You were asked by your boss to design and develop this system as quickly as possible based on the company's requirements with your own assumptions. You will be the project manager for this project, with the assistance of two other junior programmers. Tasks: Draw a network diagram for the network that will house the BookWorld – Online Book Ordering System. The online form will be a website that will be stored in the web server. The webserver will be protected by a firewall and be placed in what is known as the demilitarised zone of DMZ. Inside the DMZ are other servers such as the email server, DNS server, database server and application server. All these servers are connected via a switch. An edge router connects the network to the Internet. The other communication path from the firewall goes to the internal network. Here’s a simple DMZ configuration: image.png
