A version control is the practice of tracking and managing changes to software code. In Information Technology, we manage information across a lot of different files . The software developed must be maintained and this involves adding some new codes, deleting some, commenting some lines of code and modifying others. Other times we develop new version of the software that we expect to replace the old one.
When changing software files, it is very important to keep detailed historical information for changes made in the file because anything can go wrong when you change a software files.
Few weeks after you make changes, you may not have an idea what changed and so it is important to have a mechanism where you and your team can track what was modified and when incase there is need for troubleshooting.
Version control provides a documentation trail that will let you and your team know why the infrastructure is the way it is and provides you with mechanism for undoing changes where necessary. Version Control is very hardy in software development as it helps reduce greatly the errors and bugs that maybe introduced when we change a software file.
To avoid headaches involved in broken codes due to changes done, you can use a version control system to easily roll back your code to a version that was working before the change that caused the breakdown were done.
Version control helps us revert our system to a particular state that was working at a particular moment.
It is always safer to go back to a software version that had been working correctly before the change was made so as you can fix problems that occurs in changes without problems of a broken non-working systems when you are trying to solve issues. This gives you time to carefully examine the code instead of making so many quick fixes just to keep the system running.
Version controls are crucial in maintaining healthy codebase for IT resources and for enabling many people collaborate on the same coding projects smoothly.
Examples of version control systems includes:
- Git
- Concurrent Version System (CVS)
- GNU Bazaar
- Monotone
- Azure DevOps Server
- Apache Subversion
- Source Code Control System
- Microsoft Visual SourceSafe

- Panvalet
- Rational ClearCase
- Surround SCM
- Revision Control System(RCS)
