This is an overview of architectures, models, and examples.
Version control systems, or source management systems, are an important aspect of modern software development. Not using one is like driving a car too fast: it's fun and you might get to your destination faster, but an accident is inevitable. This article provides an overview of Software Configuration Management (SCM) systems and their benefits. It also reviews the most common SCM architectures. Finally, it explores some of the new approaches that are available and how they differ from the earlier methods.
Source control typically implies the control of source code and associated files, whereas source management can apply to any type of asset. A Web site consisting of Hypertext Markup Language (HTML) and binary image files, general text documents, or any other file is a candidate for revision control by an SCM system.
