Research and Implementation of the Optimal Design Pattern of Electronic Commerce Based on J2EE

Analyzed and recomposed to J2EE architecture, and during research of design pattern, the document bases on existing frame for achieving more application-layer reuse to engineer framework, and forms an optimal design pattern of electronic commerce. The pattern is actualized in on-line shopping system found on J2EE. The experiment results show that it reduces system development cycle, optimizes system structure, enhances the system's performance, and decreases the risk and the cost in software development when the framework and design pattern are combined artfully to use on electronic commerce
