CoMet: A tool using CUMM to measure unused component members

Abstract:

Software component technology has become a major pillar of the IT evolution. The benefits of this technology, such as reuse, enhanced quality and relatively short application development time, have been key drivers of its industrial adoption. However, in its progress towards maturity, component technology has suffered from a number of limitations, such as unused component members (data and functionalities). For instance, a reusable software component incorporates a set of members, a size-varying subset of which is actually used to satisfy the functional requirements of a particular software application. This means that a complementary subset of unused members will persist in the deployed application, where this subset provides no functional value to the host application. Furthermore, these unused members can consume memory and network resources and might compromise application integrity and/or security if they are exploited inappropriately. In this paper, we propose CoMet, a prototype tool which applies CUMM (Component Unused Member Measurement) method to measure unused component members (attributes and functionalities) and their usage percentages in a software application. © 2006 IEEE.
