Design And Implementation Of Project Management System Based On J2EE And MVC

In the engineering project of telecom enterprise, there exist such problems: numerous history data, difficulty of management, great time and space span, complicated flow, low efficiency of project management. Therefore it is urgent to develop an engineering project management system to solve these problems above.This thesis does a research on object-oriented software modeling with UML to collect the requirement, set up analyzing model and design the model in order to realize the smooth transition. J2EE is the technology used to realize the system. And in the transition from system analysis to designing phase, the thesis adopts MVC (Model-View-Controller) to optimize the architecture of the system. In the stage of system designing and realization, the thesis describes how to set up system model with UML and realize the system with J2EE technology.The thesis proposes a whole framework and system requirements of project management system of telecom industry in the view of constructing the standard project management system.The main work of this thesis is as follows: Firstly, according to the enterprise edition system architecture provided by the J2EE standard, we analyze and design the system through use case modeling, action modeling and structure modeling., Secondly, based on the function requirement of the trunk line business in the enterprise, we present the use case diagram, sequence diagram and class diagram. Thirdly, based on the model we propose above, we construct the general code framework by using the Eclipse tool, and program the whole detailed code based on it. The system we propose can primarily satisfy the requirements of the project management of telecom industry. The system implement eight major sub modules: requirement plan, project setup, feasibility research, design, approval, contract management, project management and finance management. The system has an effective management of all kinds of resources in telecom enterprise, and greatly simplify the process of some operations, curtail the processing time. Furthermore, most of the statistic report will be created automatically in the last stage of finance accounting, thus improve the efficiency and accurateness of statistic.
