Abstract: The implementation of a three-tiered J2EE application is proposed with multi-design patterns and application architecture in distributed architecture through an item bank based on IRT.It is practically easy to implement,maintain,and loose coupling multi-tiered application architecture with the ability of distributed deployment.It is a new approach for IRT item bank based on Web.
