基于J2EE的网络考试系统设计与实现

针对现有网络考试系统中页面逻辑、业务逻辑和数据逻辑混杂在一起，系统耦合性高，重用性、可维护性、可扩展性差以及Web用户界面响应灵敏性低等方面的问题，利用Struts框架、Hibernate．Ajax技术结合J2EE四层体系设计和实现了一个网络考试系统。此系统分离了页面逻辑、业务逻辑和数据逻辑，达到了结构上的松散耦合，提高了重用性、可维护性、可扩展性，实现了系统的动态更新页面和实时响应。较好地满足了教学需要，提高了考试评估的科学性和准确性。

Design and Implementation of Network Examination System Based on J2EE

Aims at the presentation logic,business logic and data logic mixed up together and high coupling,poor reusability,maintainability,scalability and the low sensitivity of web user interface's response in the existing network examination system,use Struts framework,Hibernate and Ajax combined with J2EE four-tier system to design and implement a network examination system.This system separates presentation logic,business logic and data logic,implements loose coupled of the structure,improves system's reusability,maintainability,scalability,implements the dynamic update of pages and real-time response in system.This system better meets the needs of teaching,improves the scientificalness and accuracy in examination assessment.
