Design And Implementation Based On WEB Of Digital Trunking Software Support System

With the rapid development of network technology, technology building enterprise distributed application has become more mature; in particular, J2EE technology proposed by SUN. It has been increasingly applied in the conformation of enterprise application systems. However, due to the complexity and diversity of the J2EE technology, technicians often do not know how to apply and assemble this technology.If the technicians apply technology in the incorrect manner, even if they achieve the business logic, several problems may still occur such as low performance, low scalability, close coupling, and low software duplication.Thus, the emphasis on my research thesis is the assembly of the software system achieving high expansibility, and facile maintenance, the improvement of the performance, and the implement of the efficient and flexible web applications based on J2EE.To overcome the problems and implement efficient Web application,this paper puts forward new software system according to MVC pattern and web application characteristic,It can solve many problems of web application and improving the system's flow and function partition. In addition,controller is the most importance,so the thesis also design and implement it according the thinking of design pattern ;then analyzes EJB technology from optimized database access,design pattern etc and bring forward some strategies and methods about how to build efficient business tier.Finally IDEN.VPN Digital Trunking Software Support System is developed according to object-orient software engineering thinking and some strategies and methods proposed by the thesis, In the process of achieving system function, the emphasis is probing into how to assemble and apply technology reasonable and providing a new thinking threat and method contributing to build high effective and flexible J2EE application.
