lähdekontrollia

Lähdekontrolli, often translated as source control or source code management, is a system that manages changes to a piece of computer code over time. Developers use source control to track revisions, revert to previous versions, and collaborate with others on software projects. It is an essential tool for any software development team, regardless of size.

The most common type of source control system is Git, which is a distributed system. This means that each developer has a full copy of the repository on their local machine, allowing for faster commits and more flexible workflows. Other distributed systems exist, but Git has become the de facto standard. Centralized systems, like Subversion, were more prevalent in the past, where a single central repository held all the code.

Key features of source control include versioning, branching, and merging. Versioning allows developers to see a history of all changes made to the code and to revert to any previous state if necessary. Branching enables developers to work on new features or bug fixes in isolation without affecting the main codebase. Merging is the process of integrating changes from one branch into another.

Benefits of using source control are numerous. It improves collaboration by providing a clear way for multiple developers to work on the same project simultaneously. It enhances code quality through easier code reviews and the ability to quickly identify and fix bugs. It also provides a backup of the codebase, protecting against data loss. In essence, source control is a fundamental practice for professional software development.
