Reifying configuration management for object-oriented software

Using a solid Software Configuration Management (SCM) is mandatory to establish and maintain the integrity of the products of a software project throughout the project´s software life cycle. Even with the help of sophisticated tools, handling the various dimensions of SCM can be a daunting (and costly) task for many projects. The contribution of this paper is to propose a method (based on the use Creational Design Patterns) to simplify SCM by reifying the variants of an object-oriented software system into language-level objects; and to show that newly available compilation technology makes this proposal attractive with respect to performance (memory footprint and execution time) by inferring which classes are needed for a specific configuration and optimizing the generated code accordingly, We demonstrate this idea on an artificial case study intended to be representative of a properly designed OO software. All the performance figures me get are obtained with freely available software, and, since the source code of our case study is also freely available, they are easily reproducible and checkable
