A software metric system for module coupling

摘要: Abstract Low module coupling is considered to be a desirable quality for modular programs have. Previously, has been defined subjectively and not quantified, making it difficult use in practice. In this article, we extend previous work reflect newer programming languages quantify by developing general software metric system that allows us automatically measure coupling. We have precisely the levels of so they can determined algorithmically, incorporated notion direction into levels, accounted different types nonlocal variables present modern languages. With our system, between all pairs modules particular with other an entire system. implemented measures procedures arbitrary C analyzed several well-used systems various sizes.
