What Does Source Code Manager (SCM) Mean?
A source code manager (SCM) is a software tool used by teams of programmers to manage source code.
SCMs are used to track revisions in software. Each revision is given a timestamp and includes the name of the person who is responsible for the change. Various revisions may be compared, stored, and merged with other revisions.
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.
