Developing Java EE Applications Based on Utilizing Design Patterns

Design patterns provide an efficient way to create more flexible, elegant and ultimately reusable object-oriented software. Thus their correct application in a system's design will significantly influence its reusability, flexibility, extensibility and maintainability. In this paper, we explain how design patterns are selected and implemented in a Java enterprise application naming Piloting management system based on a model-view-controller model and integration of open source frameworks such as Spring and Hibernate. Then we adopted several appropriate design patterns in the design process and validated the feasibility of this framework model in the implementation of Attemper subsystem.
