Research And Application Of Business Component's Extraction Method In Immature Domain

CBSE change the software development radically and has been a landmark in the process of software engineering development, component-based development is a process of developing application rapidly with the exist components, which can lead to higher software productivity and quality. But how to produce the reusable components and how to use these components appropriately is the problem with which we must concern. The research of this paper mainly concentrates on how to produce the reusable business component in immature domain.Firstly, the basic concept of component is introduced, then we discuss the1characters of other software reuse technologies and relationships between the component and these technologies. Secondly, under the background of enterprise information construction domain, we make research on how to make component-based development in the domain without enough reuse asserts and enough domain knowledge, and we present a process of how to acquire the business component, from specifical software architecture till the construction of business model then identifying and designing business component with improved cluster algorithm. Lastly, Facing the concrete encountered problems in the enterprise information construction domain, we give a validation on our theory and solve the practical application problems in the domain.
