Versioonikontrollsüsteemide

Version control systems, also known as revision control systems, are tools that help manage changes to source code over time. They allow multiple people to work on a project simultaneously without overwriting each other's changes. Version control systems keep track of every modification to the code in a special kind of database. If a mistake is made, developers can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members.

The most common types of version control systems are centralized and distributed. Centralized version control systems, like Subversion (SVN), use a single server to store all the versions of a project's files. This makes it easy to coordinate changes and manage access permissions. However, it can be a single point of failure, as the server must be available for developers to commit changes.

Distributed version control systems, like Git, allow every developer to have a full copy of the entire project's history on their local machine. This makes it possible to work offline and commit changes locally before syncing with a central repository. Distributed systems also make it easier to branch and merge changes, as developers can work on separate branches independently and later merge them back into the main branch.

Version control systems also provide other useful features, such as the ability to tag specific versions of a project for release, and to easily revert to previous states if something goes wrong. They also facilitate collaboration by allowing developers to see who made specific changes and why, and to discuss changes through integrated tools.

In summary, version control systems are essential tools for modern software development, enabling teams to work more efficiently, collaborate effectively, and maintain a clear history of changes to their codebase.
