verziójelölés

Verziójelölés, often translated as versioning 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 is a fundamental concept in software development, document management, and many other fields where iterative modification is common. The primary purpose of versioning is to allow users to revert to a previous state of the data, to compare changes over time, to see who last modified something that might be causing a problem, and to identify when a problem occurred.

There are various approaches to versioning. Simple versioning might involve manually renaming files with sequential numbers, such as document_v1.doc, document_v2.doc, and so on. However, this method quickly becomes cumbersome and prone to errors, especially with many collaborators or frequent changes. More sophisticated systems, known as version control systems (VCS), automate this process. These systems typically store a history of changes, allowing users to check out specific versions, merge different lines of development, and track the evolution of a project.

Popular version control systems include Git, Subversion (SVN), and Mercurial. These systems are essential for collaborative projects, enabling teams to work on the same codebase simultaneously without overwriting each other's work. They provide a structured way to manage code, track bugs, and deploy new features. The concept of versioning extends beyond code to include documents, design files, and any other digital asset that undergoes modification.
