Version control systems are tools that help software developers track and manage changes to their code over time. These systems allow developers to keep a record of every version of their code, as well as revert back to previous versions if necessary. They also enable multiple developers to work on the same codebase simultaneously, without the risk of overwriting each other's changes.
There are many different version control systems available, including Git, Subversion, and Mercurial. Each system has its own unique features and capabilities, but they all serve the same general purpose of helping developers manage and track changes to their code.
One of the primary benefits of using a version control system is the ability to roll back to previous versions of the code. This can be helpful in situations where a bug is introduced or a feature is not working as intended. By reverting to a previous version, developers can fix any issues and then continue working on the code from that point.
Another benefit of version control systems is the ability to collaborate with other developers. By using a version control system, multiple developers can work on the same codebase at the same time, without the risk of overwriting each other's changes. This makes it easier to collaborate on projects and ensures that the code remains organized and up-to-date.
centralized vs decentralized version control systems
There are two main types of version control systems: centralized and decentralized. Centralized version control systems, such as Subversion, rely on a central server to store all versions of the code. Developers commit their changes to the central server, which keeps track of every version of the code.
Decentralized version control systems, on the other hand, do not rely on a central server. Instead, each developer has a complete copy of the codebase and its entire history on their own machine. Changes are made locally and then pushed to other developers' machines. Git is an example of a decentralized version control system.
One of the main advantages of centralized version control systems is their simplicity. Because there is only one central server, it is easier for developers to collaborate and keep track of changes. Centralized systems are also generally easier to set up and maintain.
However, decentralized version control systems have several advantages as well. Because each developer has a complete copy of the code-base and its history, there is no single point of failure. If the central server goes down or is lost, the code is still safe on each developer's machine. Decentralized systems are also generally faster and more flexible, as developers can work offline and commit their changes whenever they want.
In this series we are going to look at these Version control systems and get to know them in full length as well as their differences. stay tuned and happy coding.
