Today, e-commerce is well-developed, more and more people choose the Internet to buy something. To address this trend, I thought of doing on a network of bookstores to buy books. The book store mainly provides book Sales function, using a B / S structure, that is, a server to provide services can host multiple domain names by visiting bookstores to browse the network of books, and can be in accordance with the wishes of the book to buy.
In the system I achieve a total of four modules: a user registration module, the book browser module and display module Book inquiries Cart module. The four modules provide the user services to browser books and buy them. To achieve the system, I choose three tiers, because the three tiers to provide for my system in the preparation of a clear train of thought. Applications also increased the three tiers of the process I scalability. Upon completion of the process of the system, I have gradually deepened the three tiers for the understanding of design Book store. Because of Based on the characteristics of the three tiers, the network is naturally achieved Bookstore B / S structure, much in line with the popular J2EE design patterns.
