Complexity Metrics for Component-based Software Systems

In recent years, the software engineering community has put considerable efforts into the design and development of component-based software system (CBSS) in order to manage the software increasing complexity and to maximize the reuse of code. This paper presents some of such efforts by investigating the improved measurement tools and techniques, i.e., through the effective software metrics. Upon the research on the classical evaluation measures for software systems, we argue the traditional metrics are not suitable for CBSS. Therefore we provide an account of novel software measures for component by adequate coupling, cohesion and interface metrics. The complexity metrics combined with three metrics on the CBSS level is also investigated. The advantages of our method are discussed as well through a case study in this paper.
