Analyze And Carry Out The Information System Of The Project Risk Management Bases On MVC Model And Coupling-separation Thought

The project risk management is the result which on the foundation that the economy and society unit recognizers estimate and appraises the risk of their activity of producing manages optimums and organizes the various managements' technology of risk, the effective control of risk implementation and to appropriate handle risk. It is the course which uses the minimal cost to get the biggest guarantee of safe. The management work of project information datum is the important link of project risk's management. The purpose is going to make each department and employees of the unit can use the resources of item information in the scope which certain biggest limit inside, to promise every department of this project can implement themselves' availably.In the our country, the information resources of the project business enterprise constructs just start, there are some problems which influences the information public realization of the item business enterprise, limit the development of electronic commerce, holds in the share and the comprehensive use of information. Therefore, to strengthen the research that constructs the resources of project's information and the realization of the system is the important and urgent mission which is put in front of us.This text sets out from the actual work, uses the coupling-separation thought to analyze the actual requirement and the business process of the information system of the project risk management, and combines MVC model to analyze and carry out the information system of the project risk management. Textual innovation with main work as follows:1. This text on the base of discussing the project's background of the project risk management information system and the problems of the development design, analyzed the requirement of function and no functions. And then combines the analyses of coupling's granularity to make a particular explanation by the form of activity diagram and use case diagram.2. On the base of analyzing the requirement of system and bring forward the designed goal and principia of the system, respectively designed the system business configuring and the data configuring. The business configuring mainly calculates the expansibility,repairable,reusable and the problem of function. Therefore, used the MVC model and the Struts configuring, designed and analyzed the function of every layer. The data configuring discussed the design of Hibernate. At the last, the text has given a dynamic activity function of the system.3. On the base of designing the system's whole structure, particularly designed the system. To particularly design by the coupling-separation thought and MVC model, and concretely described the MVC designing of every module. In the setting up system model, for understanding the design of system better, I analyzed the function and position of the information system, gave the whole structure diagram of system. After managing to follow the whole structure, for the requirement analysis, designed the Struts and Hibernate structure of every module and tables of the database.4. On the base of finishing the particularly design, I realized the function of every module. Gave the main interface of system and the realization interface of every module, realized the arithmetic of every module's business logic and data structure; By the actual requirement of system, designed and realized every DAO class and configuration files of Hibernate structure, and explained the other arithmetic which comes down to the system.In the end, this text made a simple introduction of MIS's applied circumstance, and put forward an outlook for the further improvement of the system.
