IDENTIFYING BUSINESS COMPONENTS FROM BUSINESS MODEL: A METHOD BASED ON FEATURE MATHCING

Identifying reusable business components from business model is the premise of Component-Based Software Development (CBSD). In CBSD, business component is the basic unit for reuse and it provides a coarse-grained functionality. A business component typically consists of related elements that possess similar features. This paper proposes an approach to business components identification based on features matching. In our method, the concepts of feature and equivalent feature relation are presented, and the rule of judging equivalent feature relation and the algorithm of parting feature set are given. To identify reusable business components, a hierarchical clustering technique is proposed. In the process of clustering, we give the formula of calculating similarity among a set of elements that extends Sorenson Coefficient. Finally, a tool RBCET is built using this method to help reusable business components extraction from domain business model.
