Version Control Systems enable users in storing source codes, documentations, and help in managing the development of the software project. The system makes project development easy and fast by tracking and controlling the changes made by users. It also enables developers to work collaboratively on the same project, tracks the modifications made by each individual, and creates its version. The main purpose of using the best version control systems is collaborative and fast and detailed documentation.
Version control systems offer the method of managing several developers who work collaboratively and track their work. Version control systems have two major approaches, namely, Centralized version control system (CVCS) and Distributed version control system (DVCS). Both the types of version control are widely implemented across the globe. However, CVCS is the most commonly utilized version control.
Centralized Version Control System (CVCS)
Centralized version control systems enable developers to work on the same project at the same time without facing any issues. With CVCS, it is possible to store the main set of documents history. It keeps track of all the documents and saves the information in a local repository. All the versions of the files are saved under revision control in the database. The system is called centralized, as there is a single central server that stores the versions database. Developers get all the information about their projects on their local computer that is constantly synced with the main server.
Distributed Version Control System (DVCS)
Distributed version control systems are designed especially for open source software projects. The DVCS enables branching and merging and lets users work in two ways by storing documents on the local repository as well as by synchronizing the documents to the server. With this approach, developers can work individually on the same project and can share their work with the team by synchronizing the modifications made. The work done in DVCS is comparatively faster than that in CVCS, as the files are stored locally. These are more widely trending as developers can work on files without the need for network connection.
Centralized Version Control System (CVCS) vs. Distributed Version Control System (DVCS)
In CVCS, a developer needs to get the local copy of files from the server and make modifications on the central server itself.
In DVCS, a developer can download the files on their local computer along with the history. Changes can be made on the local file, which can be then uploaded on the server. This process is usually called branching and merging.
Ease of use
CVCS are easy to understand along with being quick and easy to setup. It does not take much time to get a hang of the system.
DVCS are somewhat complex to understand for beginners. There are numerous commands that users need to keep in mind while working on this system.
It is comparatively hard for developers to work on branches in this system as they can face merge conflicts.
DVCS makes it easy for developers to work on branches with lesser conflicts.
In CVCS, there is continuous need for network connectivity to keep working on the project as the changes are made directly on the server.
In DVCS, a local file is downloaded. Therefore, users do not need network connectivity and can have access to the file when offline. The changes made can be synchronized to the server at a later stage.
CVCS is comparatively slow as developers work directly on the server.
DVCS is fast, as developers usually work on a local copy of the file without the need fora server each time.
