Research Of Component Composition Method On Iterative Developing Process Model In Immature Domain

The Component-Based Software Engineering have change the development of software basically during the period of which grate development appeared at software technology, it become one of the milestone at the software engineering improving period. The appearance of the software reuse technology make a grate improves on the developing speed and qualities of software reduce the cost of software. People know it gradually that software reuse if the only way to implement the industrialization of software. But it not enough to satisfy users highly requirement when we only use the simply reuse. People began to think about that software can be made by several parts such as the hardware is plugging in together with several hardware parts, every part has its specialty function. So, component composition become the direction of software development and reuse. This article produces the research about component composition method in immature domain mainly. This article produce the basic concepts of software engineering and component technology firstly, and discuss characteristic of software reuse technology and the advantage of iterative developing progress, and some knowledge about domain project. It also analysis the exist method of component composition. It brings forward how to achieve component composition in immature domain aim at serious short of resource and the lack of domain knowledge with the background of teaching evaluates system. And it provide a dynamic method of component composition in immature domain which can adapt the change of this domain and can also maintain the stability and security of the system, it resolves the actual problems of the system development.
