Coupling Metric to Measure the Complexity of Component Based Software through Interfaces

Component-Based Software Development (CBSD) is becoming the trend for software development by using the existing component. The existing components may be black box in nature. There are many software complexity metrics proposed by various researchers which are based on the source code of the software. But these traditional metrics are not applicable for black box component because source code is not available due to the black box nature of component. Black box nature of components creates the difficulty to measure the complexity of software. In this paper metric has been proposed to determine the coupling complexity of software which is developed by using black box component. The proposed metric is based on the interfaces between the components in the component-based system.
