J2ee-based Interactive Learning System Research And Design

The interactive study system is constructed many aspect systems. The paper mainly discusses an aspect of the interactive study system from the online examination. How to use the advanced technical construction to design and study the reliable and stable algorithm of the examination system is the key to the construction of the online examination system. It is also a primary tendency of using the technology development of the Struts frame based on the Web system which the software will be developed. The paper mainly explains how to use the Struts frame to develop a system with optimized features, strong extendibility, powerful algorithm and reliable security system based on the J2EE.The paper introduces J2EE and the design pattern of MVC, and summarizes the Struts technical. The paper has effectively realized various function modules of the online test from the perspectives of the design of test bank, the theory of construction of test bank, and of the algorithm of the test bank design, and the detailed functional design of the online test. Especially, combining the normal distribution theory, it has designed the algorithm of the automatic test production, and it has given a detailed plan. The paper also explains the significance of the test system as well as the system function.The system architecture mainly involves the total system structures, and parts of the system, and the way how they are combined, and the system and design module in the system. We primarily classify the layers and module; meanwhile, we reasonably distribute them into different layers, then describe all kinds of relations among layers and modules in the system.We consider the potential requirements as possible as we can when designing the system, and we keep the interface of extensibility as possible as we can. We improve the extensibility of the system by the method of object-oriented design. We can easily realize the extensibility of the system by the object and by the realization of interface, and by the process of object creation with configuration of "object factory".
