USING BRIAND’S PROPERTIES TO THEORETICALLY VALIDATE LI INHERITANCE METRICS

Abstract

Theoretical validation of metrics meant to ensure that the metrics work as it should be and measure what it intended to measure. There are a lot of validation techniques, most Object Oriented metrics where validated against Weyuker’s property, However, Weyuker’s property been criticized by number of researchers when it used to validate OO metrics. This paper will present theoretical validation using Briand’s et al length and size properties of Li inheritance metrics which are Number of Ancestor Classes (NAC) and Number of Descendent Classes (NDC), who came up with new OO metrics, which measure different attributes such as Coupling, Complexity and Size, after finding out the limitation in Chidamber- Kemerer measures suite of object-oriented design.
