Business component identification of enterprise information system: a hierarchical clustering method

Business component identification is recognized as one of the greatest important phase in the process of component-based software development (CBSD). This paper presents an approach to identify business components from domain business model. First a domain business model of enterprise information system is proposed, and it is the input of business components identification phase. To identify business components, a hierarchical clustering technique based on graph is proposed. This method proposed differs from traditional clustering technology, and it uses the edge strength to substitute for edge weight. In the process of business components identification, we consider cohesion, coupling, granularity and number of business components. To acquire high quality business components, we give the rule of evaluation of business components, which consider mainly non-functional factors such as capacity, cost, security etc. Finally, quality management subsystem is used as example to describe the method of business component identification
