Techopedia Explains Source Code Manager (SCM)

Using revision control software, a programmer or team of programmers may use several approaches for software development. Locally, developers must all use the same computer system, which may be the revision control system. In a distributed model, developers work directly with a local repository, where their individual source code revisions are collected. The developers then update the central repository with their local revisions so that revisions can be shared among developers.
