Research And Implementation Of The E-Commerce System Based On Ajax

Information accelerates economic globalization, Production and life style of human is undergoing profound changes, In the wave of information and economic globalization, With efficient,quick,convenient advantages and a brand new enterprise business idea,means,environment, E-commerce has become a significant application field and hot spot of research.This paper mainly researches on application framework of E-commerce System, Investigates improved scheme of non-functional requirement which provides availability,scalability and maintainability for the E-commerce System.By analysing lacks of availability of user interaction existing in traditional request / response way, Presents integrating Struts framework with Ajax that asynchronous request / response access technologies for improving system availability; Uses hierarchical design idea of classic MVC design pattern for code optimization of Client; Implements quickly system scalability requirement caused by change of user demands and keep the extend of code changed at a minimum;In addition the system also uses strong exception mechanism and log records function of the Java language, further ensuring the safety and reliability of the system.In the process of developing the Online bookstores E-commerce System, the standard UML OOA is adopted for systemic analysis and design .and technologies mentioned above have been implemented in the system. The effect is that greatly improves availability and scalability of the online bookstore Web-based systems, and benefit to maintaining and upgrading systems later.Therefore, the issues provided by this paper have reference value for constructing a high-availability, scalability and intelligence of the Web Application.
