Selection Of Components Using Rateof-Reusability And Matrix-Of-Reusability

Reusability is the focal-point of component-based software engineering. This paper offers a selection measure for components, utilizing the reusability property of component-based applications. This work introduces a metric named 'Rate-of-Reusability', to explore and examine the reusability behaviour of various classes of components including fully-reusable and partially-reusable components. Further, Rate-of-Reusability is used to draw a 'Matrix-of-Reusability', which contains the reusability rate for defined categories of components. The Matrix-of-Reusability plays a vital role in the selection of components, specifically when we have more than one component available for reuse. Matrix-of-Reusability makes the selection process of components faster and more efficient. Values obtained through proposed metrics and matrix are stored as the component's attribute and can be used in future for developing component-based applications in a shorter period of time. Lines-of-code is used as the base metric for Rate-of-Reusability and Matrix-of-Reusability.
