Software Configuration Management (SCM) is an important discipline in professional software development and maintenance. The importance of SCM has increased as programs have become larger, more long lasting, and more mission and life critical. This article discusses the evolution of SCM technology from the early days of software development to the present, with a particular emphasis on the impact that university and industrial research has had along the way. Based on an analysis of the publication history and evolution in functionality of the available SCM systems, we trace the critical ideas in the field from their early inception to their eventual maturation in commercially and freely available SCM systems. In doing so, this article creates a detailed record of the critical value of SCM research and illustrates how research results have shaped the functionality of today's SCM systems.

Software configuration management (SCM) is an important discipline in professional software development and maintenance. The importance of SCM has increased as programs have become larger, more complex, and more mission/life-critical. This paper presents a brief summary of a full report that discusses the evolution of SCM technology from the early days of software development to present, and the specific impact university and industrial research has had along the way.

This paper describes research associated with the development and evaluation of Odin-an environment integration system based on the idea that tools should be integrated around a centralized store of persistent software objects. The paper describes this idea in detail and then presents the Odin architecture, which features such notions as the typing of software objects, composing tools out of modular tool fragments, optimizing the storage and rederivation of software objects, and isolating tool interconnectivity information in a single centralized object. The paper then describes some projects that have used Odin to integrate tools on a large scale. Finally, it discusses the significance of this work and the conclusions that can be drawn about superior software environment architectures.
