摘要

如今電子商務(wù)十分發(fā)達(dá)，人們?cè)絹?lái)越多的使用網(wǎng)絡(luò)來(lái)購(gòu)物。針對(duì)這個(gè)趨勢(shì)，筆者就想到了做一個(gè)網(wǎng)絡(luò)書城來(lái)賣書。這個(gè)網(wǎng)絡(luò)書城主要提供購(gòu)書功能，使用的是B/S架構(gòu)，即一個(gè)服務(wù)器提供服務(wù)，多臺(tái)主機(jī)可以通過(guò)訪問域名來(lái)瀏覽網(wǎng)絡(luò)書城的圖書，并且可以根據(jù)意愿，選購(gòu)圖書。
該系統(tǒng)總共實(shí)現(xiàn)了四個(gè)模塊：用戶注冊(cè)模塊，圖書瀏覽模塊，圖書查詢模塊和顯示購(gòu)物車模塊。這四個(gè)模塊給用戶提供了完整的瀏覽選擇圖書和購(gòu)買圖書的服務(wù)。
實(shí)現(xiàn)這個(gè)系統(tǒng)，是使用三層模型來(lái)做，因?yàn)槿龑幽Ｐ徒o系統(tǒng)提供了清晰的編寫思路。應(yīng)用三層模型也提高了我的程序的可擴(kuò)展性。在完成系統(tǒng)的過(guò)程中，設(shè)計(jì)者也逐步加深了對(duì)三層模型設(shè)計(jì)方案的理解�；�于三層模型設(shè)計(jì)的特點(diǎn)，該網(wǎng)絡(luò)書城自然而然實(shí)現(xiàn)的是B/S架構(gòu)，非常符合時(shí)下流行的J2EE設(shè)計(jì)模式。

ABSTRACT

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.
