In order to optimize resources and to collaborate between dynamic alliance enterprises, functions on dynamic alliance system were designed and system was implemented successfully on J2EE(Java 2 Platform Enterprise Edition). The system was four-tier browser／server system architecture according to J2EE framework. And design patterns such as Session Facade, Composite Entity, value object etc were applied. The system has good reusability, maintainability, and reduced network load and improved resource utilization because of the system design and implementation approach. The geographically dispersed alliance-enterprises could use the system as a reference in design, manufacture or assembly collaboratively complex products (such as auto parts).
