Version Control System is the system that allows managing the multiple revisions of the same unit of information. That might be any documents, source file, of HTML code or any other large software developing project. Version control system allows the multiple users to cooperate and share the same file in the server.  Then there might be the question, why version control system is necessary?  Of course, while editing the same file from the server, it can happen that many person are editing the same portion of the file, there might be the duplication of the same file. In this situation version control system plays the key role not to happen so.  Version control system lock the main file from the server if one person is editing that file or it may shows the warning notification signal that somebody is editing the same file.


Moreover version control system is the only way to track the changes in the file. This is very important in the software development process. While releasing the different version of the same software, if the latest version suffers some bug or problem, developers can easily look over the changes that were made in the newer version. This means version control system not only systematized the data but also helps to solve the problem very quick.
