FAQ: What Is Version Control and How Can You Use It?

Why is it important to have version control?

Any multinational company may encounter a number of issues, such as employee collaboration, storing multiple versions of files as they are created, and data backup. To be successful, a company needs to overcome each of these issues. At this point, a version control system enters the scene. We’ll learn the fundamentals of that system and its advantages in this tutorial.

Version Control is a system that tracks changes made to a file or set of files, as the name suggests. The term “system” refers to a group of software tools that enable the development team to monitor source code updates as needed. The system keeps track of all file modifications so that, if necessary in the future, a particular version can be rolled back.

Keeping everyone on the team informed is the version control system’s responsibility. Most importantly, it guarantees that everyone on the team can work simultaneously on the same project while using the most recent version of the file.

Why use version control?

There are many reasons why development teams use version control techniques and software. Version control procedures primarily assist the development team in monitoring and controlling any significant project changes. Version control, for instance, enables the rest of the team to access the earlier version of the application and view the changes if a developer modifies a key feature of an application that is currently being developed. By giving everyone access to the most recent versions of the source code or the project itself, version control also assists the team in maintaining cohesion. This can increase the team’s productivity and cooperative efforts.

Additionally, version control aids development teams in avoiding duplication of effort or overriding the work of other team members. Because everyone is working on the same document, collaboration becomes easier and more effective when everyone has access to the same version of it. The following are some advantages of the software and procedures used by version control systems (VCS):

What is version control?

Development teams use version control software as a tool to keep track of the various coding or file versions that appear throughout a project. The need for tracking and managing various versions of the project becomes more urgent as development processes advance, increasing the speed and efficiency of development projects. Developers use version control software as one project management tool, but any file or source code management can contribute to the team’s overall version control efforts. For accessibility, this can entail making project backups, creating collaborative files, or putting files on cloud drives.

How do version control systems work?

The capabilities of version control systems and the specific version control efforts of teams frequently vary. A collaborative platform where teams can work on a project and automatically receive updated files, for instance, might be offered by version control software. To ensure that everyone is working on the same version, the group could also use a cloud storage service to upload, download, and edit files simultaneously. To ensure that source code and project assets are up to date with the latest versions and error-free, some teams use automated VCS services.

What are the elements of a successful version control software?

Successful version control software typically consists of several elements. These components provide a user-friendly interface for simple access and collaboration, as well as project security and consistency. Here are some key elements of good VCS:

What are the types of version control software?

Here are a few common examples of version control software:

Local data model

All local users must have access to the same file system in order to use the local data model. This guarantees that local teams have access to the same data and manages the team’s workflow. Typically, local data model software comprises two different versions:

Client server model

The client-server model requires developers to share a single repository. By tracking versions and project changes from the repository in real-time, this makes sure that the team has access to all of the data from a single location. Tasks are divided up between “clients,” or computer systems, in the client-server model, which then report changes to a single server.

Distributed model

The distributed model necessitates that developers maintain their own repository and submit updates to each repository for reporting to a single server. This facilitates the reconciliation of small project changes with more significant ones. A distributed VCS model makes sure that updates are accurate and keeps track of every change log for backup files.

Open source

Many VCS services are open source, which means that anyone can access their source code and make changes, updates, or revisions to it. Generally speaking, open-source software is more flexible and frequently free to use for both businesses and individuals. This makes it a fantastic option for developers and emerging tech firms.


Commercial licensing makes proprietary systems accessible to all users for specific purposes. These programs typically have private source code and cater to a company’s particular version control requirements. Most often, private companies create proprietary systems.


What are three reasons for version control?

Why Use a Version Control System?
  • Collaboration. Without a VCS, you are most likely collaborating on the same set of files in a shared folder.
  • Storing Versions (Correctly) After making changes, it’s important to save a version of your project.
  • Restoring Previous Versions. …
  • Understanding What Happened. …
  • Backup.

Why version control is so important?

Multiple developers, designers, and team members can collaborate on a single project thanks to version control systems. A version control system is essential to make sure that everyone has access to the most recent code and that modifications are recorded because it enables them to work more efficiently.
