revisiointijärjestelmän

Revisiointijärjestelmä, often translated as a revision control system or version control system, is a software tool that helps manage changes to files and projects over time. It records every modification made to a set of files, allowing users to revert to previous versions, compare different versions, and track who made which changes and when. This is particularly useful for collaborative projects where multiple people are working on the same codebase or documents simultaneously.

The primary function of a revisiointijärjestelmä is to maintain a history of changes. When a user makes modifications, they can "commit" these changes to the system, creating a new snapshot of the project. This snapshot is associated with a unique identifier and a descriptive message explaining the changes. If a mistake is made or a previous state is desired, the system can easily retrieve and restore older versions.

Revisiointijärjestelmät also facilitate collaboration by enabling multiple users to work on the same files concurrently. Features like branching allow developers to work on new features or bug fixes in isolation without affecting the main project. Once their work is complete, these changes can be merged back into the main project. This prevents conflicts and ensures that work is integrated systematically. Popular examples of such systems include Git, Subversion (SVN), and Mercurial.
