Revisionihallintaan, often translated as revision control or version control, is a system that records changes to a file or set of files over time so that you can recall specific versions later. This allows you to revert files back to a previous state, compare changes, see who made what changes, and ultimately undo unintended consequences. It is a fundamental tool in software development, but its principles are applicable to any project where documents or data evolve.

The core concept involves storing snapshots of files at different points in time. When a change is made, the system records this modification. Users can then check out a specific version, make further modifications, and commit these new changes as a new version. This creates a history of the project, enabling collaboration among multiple individuals by managing different contributions and preventing conflicts.

Common revision management systems include Git, Subversion (SVN), and Mercurial. Git, in particular, has become the de facto standard in modern software development due to its distributed nature, speed, and powerful branching and merging capabilities. These systems facilitate teamwork by allowing developers to work on separate features concurrently and then integrate their work seamlessly. The ability to track every modification ensures accountability and aids in debugging by identifying when and where errors were introduced.
