Design And Implementation Of Accident Remote Investigation System

With the development of internet, more and more enterprise application systems are based on web. At the same time, J2EE platform, owing to its open standard and the advantage of Java technology in implementation of web application system, has become the best choice of implementation of web application system. This thesis researches how to integrate the Struts framework and EJB(Enterprise Java Bean) to design and implement a reusable, maintainable and extensible web application system based on J2EE platform by designing and implementation of ARIS(Accident Remote Investigation System).Firstly, this thesis describes J2EE platform and Struts framework in brief. Then, this thesis introduces the core design patterns used in web application systems based on J2EE platform, and especially introduces the MVC design pattern. Secondly, this thesis analyses the user's requirements and designs the modules of ARIS based on J2EE platform. In ARIS, the web tier and business tier are implemented using MVC design pattern by integration of the Struts framework and EJB. The data tier is implemented by Oracle DBMS. In this part, how to integrate the Struts framework and EJB is introduced in detail. Because the web tier and business tier are the important parts of ARIS, this thesis introduces them separately. In chapter four, the implementation of controller and view components based on Struts framework are introduced firstly. Then, the EJB components are implemented to construct the business tier. In this part, in order to implement a reusable, maintainable and extensible web application system, how to use MVC design patterns to design the web tier and business tier are introduced. In the last part of this thesis, the integration and deployment of ARIS is described. At the same time, the experiences from the development of this system are shared. Some advice is given to make the system better.This thesis combines the theory with practice and introduces a resolution which using MVC design patterns and integrating the Struts framework and EJB to develop a web application system based on J2EE platform. At the same time, this resolution also gives a good sample to develop a web application system based on J2EE platform.
