網上購物系統設計 摘　要：本網上購物系統是一個基于Internet,采用B2C(Business to Consumers)模式，并根據現有的網上購物系統的現狀而設計開發的電子商務平臺。它不但可以擴大商家的規模和市場影響力，而且可以減少企業的經營成本，提高工作效率。 本文首先介紹了網上購物系統的現狀及開發背景，然后論述了系統的設計目標，系統需求和總體設計方案，較詳細的論述了系統的詳細設計和實現。最后，本文對網 上購物系統進行了系統檢測并提出了還需要改進的問題。 本系統主要為用戶提供了會員注冊，購物車管理，用戶資料修改等功能，為管理員提供了商品管理，用戶信息管理等功能。在設計方面，本系統采用B/S三層結構，同時使用JSP技術進行動態頁面的設計，從系統的安全性和代碼的可重用性方面考慮，運用JavaBean對程序的關鍵代碼進行封裝。后臺數據庫選用My SQL數據庫。 關鍵詞：B/S結構；JavaBean；JSP； The Design of The Shop OnLine System Abstract：The shop online system is a electronic commercial platform which has been designed according to the situation of shop online system based on Internet with B2C mode. It can not only enhance the scale of shopping centre and market influence, and can also reduce the enterprise’s running cost, improve work efficiency. The thesis has firstly introduced the practical situation and the developing background of the system. And then has described the designing goal、system need and the whole designing plan, has described the detailed design and reality of the system in detail. Finally, conclusion has been drawn about the system and problem has also been raised. The system has mainly provided users with the following functions: membership registration、shopping car management、goods search、information modify etc. It has also provided managers with goods management、customer information management、news management 、ad management and so on. It has been designed with B/S mode of three-tier structure, JSP technology in dynamic page design. Considering from the security and reusing code of the system, key codes has been secured by JavaBean technology. My SQL database has been used as the background database.
