Study And Implementation Of Aviation Product System Of E-Mart Based On J2EE

With the rapid development of E-commerce, More and more attention has been paid to the development of distributed applications for enterprise. The main platform of distributed applications for enterprise is SUN's J2EE infrastructure which can help us to develop flexible, scalable, cross-platform enterprise applications. In this paper we describe the advantage of the system integration of J2EE 3-tier infrastructure firstly. And then we brought up that the design and implementation of presentation-tier and data-tier are very important in the enterprise web applications, and this paper lays emphasis on the two tiers.The paper introduced the interrelated technology of presentation-tier and data-tier in J2EE 3-tier infrastructure, and through contrasting of these technologies, the paper summarized the virtue and disadvantage of Struts, which is widely used at present. Finally, the paper make out that WEB system can be developed efficiently with Struts on the base of the requirement of building WEB system quickly which can be extended and maintained easily.The research and practice of this paper is based on the Product System of E-Mart of Aviation Data Communication Corp.. The object is, to integrate the resource properly, show our software, services of system integration comprehensively, and improve the visibility and image. More, it raises the efficiency, reduce the producers'pressure. I'm in charge of the system design and development in the team.On the base of analyzing and designing the system, we divide the system into several modules, then analyze and design the structure of each module. In the implementation, the paper emphasize the architecture of the system , adopt Struts framework in data-tier and JDBC in data management. After that, we achieve the functions of the management of users, products, shoppings, orders and then. The paper illustrates the system implementation comprehensively.After comprehensive test, the system has been put into practice and improved the efficiency and management level of Aviation Data Communication Corp..
