Section 13.3 Version Control Systems (VCS)

As software projects grow in size and complexity, keeping track of changes, coordinating teamwork, and preventing loss of work becomes increasingly important. Version Control Systems (VCS) provide a structured way to manage these challenges. They track every change made to a codebase, who made it, when, and why—allowing developers to revisit previous versions, collaborate more effectively, and recover from mistakes.

Why Use Version Control?
Version control helps with:
  • History Tracking: You can review the history of a project, see what changed, and revert to earlier versions if necessary.
  • Collaboration: Multiple developers can work on the same codebase simultaneously without overwriting each other’s work.
  • Branching and Merging: Developers can create branches to work on features independently, then merge them back into the main project once complete.
  • Backup: A central repository (often in the cloud) serves as a backup of the project, protecting against data loss.
