The Research And Implementation Of Web Application Development Framework Based On Mdr

In recent years, the emergency of new programming development technologies, such as OOP, component technology, design pattern, code reuse and so on, have improve the efficiency of programming at some extent, but it is not the essential revaluation of programming. The appearance of MDA may change this situation essentially. The main idea of MDA is to separate molding of business logic from concrete realizing technology, and emphasis the focus on the molding of user needs. The mapping process of user needs to coding will be complete by MDA automatically. Because the transformation of PIM to PSM is so difficult, so it is very hard to implement MDA in real project.In order to effectively solve the above problems, this thesis proposes MWAF, the software development framework which is built on a model-driven structure. MWAF is a secondary software development framework, which is based on the Microsoft. NET framework. MWAF is dedicated to the development of various web-based applications. On the basis of MDR's core idea, MWAF not only achieves the separation of business logic modeling and concrete coding realization, but also solves the problems of the transformation of PIM model to PSM model by workflow engine.The structure of this thesis is mainly organized as follow:Based on the studying and researching of relating backgrounds, the thesis describes the conception of MWAF and analyzes the core technology of MWAF in chapter two.In succession, the thesis describes the structure of MWAF, main function modules, concrete realizing technologies in chapter three.In chapter four, the thesis describes the real application of MWAF in a warehouse management system.From the above real project, the MWAF shows many advantages:easy to use, easy to develop, high expansibility, automatic adaptation to user dynamic needs, etc. There are high applicable values for MWAF in real engineer.
