The software product line (SPL) community defines SPLs not only by technical aspects like configurability and code reuse among product line variants, but also by the engineering process that accompanies the development. This paper discusses the question whether this engineering process is a mandatory property of SPLs; it concretely examines the Linux Kernel, which is not being developed accordi...

The analysis and measurement of current levels of software reuse are necessary to monitor improvements. This paper provides a framework for the derivation of measures of software reuse and introduces several de nitions, attributes, and abstractions of potentially measurable reuse properties. The framework is applied to the problem of measuring reuse in object oriented systems which support \lev...

We present an overview of some of the research being performed at the Norwegian Computing Center. We believe many of the problems related to software engineering in general and object-oriented development in particular result from too little attention being paid to the role of modelling, both in terms of how we understanding problems and how we attempt to solve them using software systems. We p...

The continuous demand for software of ever-increasing complexity will change our current approach to software development. In the future, the creation of software will apply increasing levels of automation to the development process. The application of componentware will become commonplace and development will move from the back office to the application user's workstation. All of these develop...

This paper argues that eecient, incremental cus-tomization of OS services can be achieved using a twofold strategy: an object-oriented architecture that relies on composition to facilitate code reuse and customiza-tion; and, an OS structure that places a minimal set of trusted functions into the kernel, with all remaining services collocated with application code in user-level protection domains.

Garment is a mechanism for abstraction and encapsu lation of languages It aims specially to make best sup port on the design and implementation of Domain Spe ci c Language DSL This approach opens some new prospects for reuse of software artifacts In this paper we include a brief introduction to Garment approach and a discussion of various possibilities of software reuse supported by the Garment...

Successful software reuse depends on many factors, adequate description of reusable software is one of them. This paper focuses on some of the inherent problems in adequately describing software for later focussed retrieval. Out of these considerations, a hybrid approach, combining well known techniques from library science with techniques based on the inherent property of software, its executa...

It is now recognized that software reuse, to be truly effective, needs to go beyond the reuse of mere code fragments or modules. The toughest design choices, and those where errors and noncompliances most often arise, concern the architecture of a software system. It is accordingly this software architecture that must be made reusable in order to make the intellectual investment that went into ...

reuse, objects, systematic process Software reuse is a widely desired and oftentouted benefit of employing object technology (OT), yet too many object-oriented (00) reuse efforts fail because of too narrow a focus on technology. This column will explore the lessons of systematic software reuse from several perspectives, such as process, organization, management, methods, technology, architectur...

38 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 ...
