Version Control, as the name implies, is a system designed to keep track of changes made to one or more files. It encompasses a variety of software tools that enable a software team to manage source code changes whenever necessary. With this system, all modifications to a file are recorded, allowing a specific version to be restored if needed down the line. This highlights the significance of version control systems.
The primary job of a Version Control system is to ensure that everyone on the team is aligned. It guarantees that all team members are working with the most up-to-date version of the files and, crucially, enables multiple people to collaborate on the same project at the same time.
Introduction
Imagine there are three developers working from different locations, each using their workstation, and they all connect to a single repository that serves as a server. These workstations interact with the repository to either commit changes or update their tasks.
Challenges
- Collaboration: With so many people spread out across different locations, it’s often necessary to communicate for specific reasons, especially when a group is working on the same project from various regions.
- Storing Versions: When a project has multiple versions, keeping track of all those commits in one place can be quite a challenge.
- Restoring Previous Versions: There are times when you need to revert to earlier versions to pinpoint the root cause of a bug.
- Figure Out What Happened: It’s essential to understand what changes were made in previous versions of the source code and exactly where those changes happened within a file.
- Backup: If a user’s system or disk crashes and there’s no backup available, all the hard work can be lost.
Why is a Version Control System Required?
Managing and Safeguarding the Source Code
A Version Control System (VCS) plays a crucial role in helping the software team manage their source code by tracking all changes made. It also acts as a safeguard against any accidental human mistakes that could lead to issues.
Keeping Tabs on Code Changes
The team working on the project is constantly generating new source code and updating the existing code. All these modifications are documented for future reference, enabling the team to trace back any issue that may arise later on.
Reviewing Previous Versions of the Code
With all versions of the code stored, developers can easily go back and compare earlier versions. This allows them to identify and fix errors without causing much disruption for the rest of the team.
Facilitating the Developers’ Workflow
A good Version Control software won’t dictate how the team should work. Instead, VCS is designed to streamline the process of making changes to the code, helping to keep frustration at bay and ensuring a smooth workflow for the developers.
Conclusion
At this point, you should have a solid grasp of the fundamentals of Version Control and the advantages it brings. You now understand why this system is so popular and why companies, whether small or large, choose to implement Version Control.
