What is Vesrion Control Systems?

A version control system (VCS), also known as a source control system, is a software tool designed to help developers manage changes to source code over time. It keeps 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 mistakes while minimizing disruption to all team members.

Here are some core concepts and benefits of a version control system:
  1. History and Tracking: VCS keeps a history of all changes made to the codebase, allowing developers to see who made which changes and when. This is useful not only for accountability but also for understanding the evolution of a project.
  2. Collaboration: Multiple developers can work on the same project simultaneously. VCS ensures that they don’t step on each other’s toes. It provides mechanisms to merge changes from multiple sources.
  3. Branching and Merging: Developers can create branches to work on new features or experimental ideas separately from the stable main code. Once the feature is tested and ready, it can be merged back into the main codebase.
  4. Rollback: If a release introduces new bugs, developers can rollback to a previous stable version of the code.
  5. Backup: The VCS repository acts as a backup. In case of accidental deletions or catastrophic failures, it’s possible to restore code from the repository.
  6. Conflict Resolution: When multiple developers edit the same part of a code, VCS highlights these conflicts and allows developers to resolve them manually.
  7. Annotation: Developers can annotate code changes with comments, providing context for each change, which can be invaluable for debugging or code maintenance.
Two main types of version control systems are:
  • Centralized Version Control System (CVCS): All users connect to a central, master repository. They get the latest version from this central place and commit changes back to it. Examples include Subversion (SVN) and Concurrent Versions System (CVS).
  • Distributed Version Control System (DVCS): Every user has a local copy or “clone” of the entire repository. They can make changes locally and then push these changes to a central server or even share changes directly with other users. Git and Mercurial are examples of DVCS.

Of these, Git is currently the most popular and widely used version control system, with platforms like GitHub, GitLab, and Bitbucket offering Git repository hosting, collaboration tools, and other related services.
