Reusability of the Software

Abstract

Reusability is the likelihood a segment of source code that can be used again to add new functionalities with slight or no modification. Reusable modules and classes reduce implementation time, increase the likelihood that prior testing and use has eliminated bugs and localizes code modifications when a change in implementation is required. Subroutines or functions are the simplest form of reuse. A chunk of code is regularly organized using modules or namespaces into layers. Proponents claim that objects and software components offer a more advanced form of reusability, although it has been tough to objectively measure and define levels or scores of reusability. Reusability implies some explicit management of build, packaging, distribution, installation, configuration, deployment, maintenance and upgrade issues. If these issues are not considered, software may appear to be reusable from design point of view, but will not be reused in practice. This paper presents an empirical study of the software reuse activity by expertdesigners in the context of object-oriented design. Our study focuses on the three following aspects of reuse : (1) the interaction between some design processes, e.g. constructing a problem representation, searching for and evaluating solutions, and reuse processes, i.e. retrieving and using previous solutions, (2) the mental processes involved in reuse, e.g. example-based retrieval or bottom-up versus top-down expanding of the solution, and (3) the mental representations constructed throughout the reuse activity, e.g. dynamic versus static representations.

Current Issues in Software Re-Usability: A Critical Review of the Methodological & Legal Issues

“…OSS has become a way for businesses to improve their own security quickly and in a cost-effective manner, noted by several authors including [24]. But if the security assets put in place fail the main issue is who will be liable, the business which is using the asset in their software, or the original author of that asset [25]. Trust is also an important concept to note.…”

Examining the Reusability of Smart Home Applications: A Case Study on Eclipse Smart Home

“…Another major challenge that arises when it comes to the reusability of the software is adapting the components that are being reused into the new environment that is being developed [27]. It is often required to parameterize the reusable components in order to integrate them in the existing environment [9,18].…”

A Machine Learning based Efficient Software Reusability Prediction Model for Java Based Object Oriented Software

“…The formal idea of software reuse instituted the development of industry of reusable software components and the industrialization of the production of application software from off-the-shelf components, as proposed by Mcllory in [2]. Not only is reuse a promising strategy for increasing quality and productivity in the software industry, but a good software reuse process also provides for increased reliability and dependability, reduced process risk, decreased cost of implementation and time to market (accelerated development), effective use of specialist and standard compliance [3]. Reusability also increases the likelihood that prior testing and use has eliminated bugs thus delivering error free software codes.…”
