Building The Next Generation Operation Support System Based On J2ee Architecture

This thesis mainly discusses the application of J2EE multi-layer system structure and frame technology through an analysis of NGOSS (Next Generation Operate Support System).J2EE multi-layer system structure is that the modern application software is built up, it is a kind of " B/S " mode, its thought stems from MVC mode thought. The frame is that kind of target -oriented technology, It is made up of abstract class and concrete class that one group cooperates each other.Because of the support of the frame, the development of support application system that can be effective. This kind of mode and technological thought were all used popularly by modern software development, it is very advanced.It is a very huge project engineering that the development of NGOSS system is built. System management , business accept , business change , statistical report form , resource management, account management, information inquiry , artificial to defend module of swindling etc. make up this system. I am responsible for such module as system management, business change , information inquiry , defending and swindling artificially developed among them. NGOSS project was carried on according to the development norm of the modern soft project strictly . Do the requirement at first, Then write out the User Case. The designer writes out outline designing and detailed design instruction .The coders encode and test finally.Through to having the compiling of research and documents and materials of the achievement ownly, and analyse about the demand for this project, this text has expounded the fact mentality of designing and system of the project are realized . moreover, it has analysed the key technology of the multi-layer system structure model of J2EE and frame of MVC model thought, If utilize NGOSS frame to carry on systematic development, can be on the premise of quality of the security system, the progress of improving the project and developing , strengthen the stalwart , flexibility and expansibility of the system, and the possible offering software isreplied and used . I have put forward some my own ideas at the end of the article...
