Notice of Violation of IEEE Publication PrinciplesMeasuring the Quality of Software Modularization Using Coupling-Based Structural Metrics for an OOS System

Abstract

The fundamental issue faced by the developers in todaypsilas environment is how to measure the quality of software modularization. In this paper a new set of metrics are proposed which measure the quality of modularization of an object-oriented software (OOS) system. A set of design principles are proposed to capture the notion of modularity and metrics are defined based on the principles. The coupling-based structural metrics measures the function-call traffic through the APIpsilas of the modules in relation to the overall function-call traffic. It is now widely accepted that the overall quality of a large body of software is enhanced when module interactions are restricted to take place through the published APIpsilas for the modules. The metrics can be tested on some large legacy-code business applications. The metrics can be validated from the results obtained on human-modularized versions of the software.
