Research On Application Framework Hierarchical Generalization Model

Today the software reuse technology has already made some progress in its field, especially in the component technology. Component based software engineering (CBSE) has been the most used term in software domain. Rapid development of application system with reused component now is the most popular development model and by this way the efficiency and quality of software can be improved. With the development of component technology, component granularity plays very import role on the complexity of component composition. How to assemble the component of big granularity? How to make the component in the same domain integrated? Application framework bring the new era of software reused technology. But how to construct application framework to make it highly reused and how to realize the ideal of building block mode. The purpose of this paper is mainly to study the problems of constructing reused application framework.. First this paper introduces basic concept of reused technology and the relationships between some software reused technology and component technology. For example, This paper introduces the relationships between design pattern,domain analysis,software architecture ,XML and component technology. This paper give a hierarchical generalization model based on the method of application framework delaminating construction and provide a new feasible method to improve reuse of the application framework. Then based on a teaching evaluation system, the paper study on the development with reused component in the immature domain which is lack of reused resources and domain knowledge. The paper gives a design resolution of application framework which suitable for big granularity is based on top-to-down analysis and down-to-top integration, construct a application system based on these technologies of application framework,component,XML and HTML according to the problem of evaluation domain, solve the practical problem of the evaluation domain.
