【摘要】 面向对象耦合性是软件质量重要的内部属性,该文分析了现有基于静态分析的耦合度量,以及其因继承和多态的使用而产生对运行时耦合度量的不足。提出了以用于系统动态建模的UML时序图为基础,定义了反映系统运行时的耦合度量指标,并通过实例验证了耦合指标定义的可操作性和实用性。更多还原

【Abstract】 Object-oriented coupling is one of the important internal attributes of software quality. This paper firstly analyses the limitations of theexisting static coupling measurement because of using inheritance and polymorphism, then defines the coupling metrics describing system run-timecoupling, which based on UML sequence diagram which used to dynamic modeling, and validates the operability and practicability of this definitionby a simple example.更多还原
