During an application development process, a quite significant part is the way developers manage to keep track of the changes been made over time. It really consists of a necessary need to be able to store and handle copies of working code versions in various stable stages, and revert back to them when bugs or problems arise. Even more, when a number of programmers work at the same project, keeping track of all changes is a one-way path. Fortunately, developers don’t have to discover their own way to do all that, as there are special software solutions, called Version Control Systems.
A version control system, or in other words a revision control system, is actually a (software) mechanism that is capable of monitoring changes performed to code files over time and storing them for future reference. Besides that, it can also save extra essential data, such as the developer who made the changes, when did they happen, what was actually modified, and other kind of historical and not only data. Moreover, such a system provides the ability to compare various versions of the code, revert to a previous version of either specific files or a whole project if needed, and eventually implement a bug-free product by tracking down any malicious code.
