China Unicom E-OMS Dispatch Subsystem System Design And Implement

China Unicom E-OMS system is manufactured by China Unicom Ltd; the system is used to achieve the overall operation of the network to maintain the production process electronic management system. China Unicom E-OMS system is divided into headquarters E-OMS system and the provincial E-OMS system. Headquarters E-OMS provides the headquarters of China Unicom network maintenance departments of the single internal circulation and production management support functions, also responsible for the operation and maintenance of various provinces actual quality score and assessment. Provincial E-OMS system will provide the provincial network maintenance companies and departments within companies and the various provincial cities between the companies for single flow transfer and production management support functions. This paper discusses the integration of the controller general framework of struts and the current epidemic of Object-Relational Mapping tool iBatis workflow and processing tools for the control of supposedly to develop Web applications.Struts can optimize developing Web application further as a framework of controller in common use. It offers a flexible Model-View-Controller method to develop Java Web. It makes display and business logic separate totally, fully realize MVC model thought.It is a current mainstream to OO development approach, but most enterprise applications have to use with the relational Database frequent and mutually. So, in the environment of development of enterprise application, the mapping of object and relation is a kind of job of consuming time. Hibernate is the ORM that programmer at present praised highly very much generally. It is the ORM of an opening source code. It carries on the object encapsulations of lightweight to JDBC. This makes Java programmers handle freely the Database by utilizing OO programming thinking.This paper develop application program of server end based on JSP and Servlets of J2EE by using struts as frame and utilizing hibernate to make data persistence. As everyone knows, JSP and Servlet are the technology based on Java and they are independent of platform. Struts are based on MVC model and makes display module separate from function module. As for new developing hibernate, it everybody's extensive concern as soon as it appears. Hibernate finish ORM (object relation mapping), so it make the interaction of enterprise application and back end Database become effective and fast. It raises also the maintainability, expansibility, portability and reusability of application system.First, the paper describes the basic design thought of Struts' frame and the ORM of hibernate technology. Second, it gives one concrete instance. At last, the paper analyses the advantage and disadvantage of using the association technology (struts and hibernate) to develop a system, moreover, the paper compares the association technology with the method of using JavaBeans to develop Web application.
