Abstract:Reusability is a desirable property of a software component. Furthermore, when building a new software product by reusing an existing component, it is important that the reusability of the reused component is not destroyed in the new product. In this paper, we use common coupling, a measure of software dependency, to represent software reusability. We have studied Darwin, an open-source operating system that was built by reusing two open-source operating systems, Mach and FreeBSD. We show that, in the course o… Show more
