Version Control System

Last updated on

One of the tools we need for software development is a Version Control System. It tracks code changes, making a way for developers to collaborate without missing their progress. Working alone or as a team, version control systems (VCS) make it simple to manage code and updates.

You'll discover how developers stay organized and productive all day by getting an overview of version control.

In this tutorial, you will understand the meaning of version control. And also some of the popular version-controlling software that every developer must know.

So let's get started with an overview.

Meaning of Version Control System

A version control system (VCS) is a tool to save changes made to files, specifically code, and track the work of multiple developers. Also, it enables more than one person to work on the same project without overwriting each other's changes. A change made by whom is for all files (you can revert to the previous version).

This can be helpful in software development because projects become complex rapidly. Some VCS tools are simple and work on a single computer. Others are advanced tools that help multi-country teams of developers collaborate. VCS fuels faster and better project management, preventing errors that waste time!

Let's move on to the following section to understand the types of version control systems.

Types of Version Control Systems

There are three main types of version control systems (VCS):

Local Version Control Systems (Source Mapping Repositories - Local)

A local version control system (VCS) is a minimal tool for tracking file versions on one computer. Users can save versions of their work, compare changes, and pick the right previous version if needed. It's a great setup for individual developers or for minor projects that don’t require collaboration.

Here is a diagram showing you how it works:

Local version control systems track changes at the level of files without having to send or interact with other people. An example of the version control used originally is RCS (Revision Control System), which manages versions by storing deltas between files.

Anyway, let's move on to the CVC system in the section below.

Centralized Version Control Systems (CVCS)

Centralized version control systems (CVCS) are those that store your files as they change over time on a central server. This is nice; all of the files and project history are kept on one server where users just check out files to work on.

Teams benefit greatly from this system as it makes sure everyone is working on the same version of their project. As other developers pull that change from the central repository, they receive your local edits in their text editor with minimal friction.

Even though CVCS has its disadvantages, if the central server is down, no one can access files. If anyone wants to update, they can’t until the central server gets back up again. Nevertheless, CVCS is still a widely used system for projects requiring straightforward collaboration. Subversion (SVN) is a common CVCS that enables multiple users to work on the same project without interfering with one another's progress.

Here is a diagram showing you what happens in it:

Centralized Version Control System

Essentially, these centralized version control systems create a very simple model for team coordination and ensure that every change to the project is consistent with all the others.

Distributed Version Control Systems (DVCS)

Enter Distributed Version Control Systems (DVCS), which distribute the entire version history of your project to every user. Instead of a single-file storage system, DVCS stores all files on each user's local machine. This allows work to continue even if the central server crashes and burns.

Here is an image showing you the process of DVCS.

The same is also true for collaborating with other developers on a project; DVCS makes this easier as well. Users can work autonomously, commit locally, and sync with others when ready. It is useful for big teams or projects with contributors located anywhere. Two of the best examples are Git and Mercurial, which were quickly established as industry standards for their power and reliability.

Now that we've explored the different types of version control systems, let's dive into some of the most widely used tools that developers rely on to manage their projects effectively.

The Common Version Control Tools

Developers use many version control tools that have different features to satisfy the requirements and types.

Git

Git is the most popular version control system at this time, especially in open-source projects. It is a distributed system where each user has a complete repository. It is suited for teams that have to manage a complex workflow, as Git supports branching and merging on the development server. GitHub and GitLab are a couple of others that provide hosting for Git repositories and include some added collaboration tools.

Subversion (SVN)

Subversion is another version control system, and SVN has been around for many years as a centralized VCS. This package is famous as it is reliable to use, like in project heat (using a central server where files are managed). SVN is commonly used in corporate scenarios, and it is one of the best at managing large binary files.

Mercurial

Mercurial is like Git and another distributed version control system. It was designed to be capable of dealing with projects of any size and to be fast and efficient. Coders who value Mercurial for its relative simplicity and ease of use have lauded the tool as a solid alternative to giants such as Git.

Perforce

Perforce is a centralized version control system that works very well with large files and complex projects, typically used in game development and engineering. It is a large codebase management tool that makes multiple teams work together. Perforce is famous for its faster processing, and hence it is commonly considered where speed and scale matter most.

Bazaar

Bazaar is an easy-to-use distributed version control system. First released in 2005, it now boasts flexibility as well. It also might be a good fit for an organization with potentially centralized and distributed workflows in its projects. Not quite as popular as Git or Mercurial, Bazaar provides an easy-to-use experience for users who prefer a different version control workflow.

In the context of UC/NC, they are hugely important tools in modern software development — where each has its unique strengths for different projects and teams. If you need a fully distributed system like Git, or something more straightforward in its centralization like SVN, there is usually some version control tool that meets your needs.

Importance of VCS

Version control is one of the most significant parts of modern software development. It comes with many advantages, helping developers and teams maintain their tasks efficiently.

  • Recording History: Version control systems (VCS) record all the changes contributed to a project. Developers can then check back in to see what changed when and by whom. If anything gets unwell, we can pinpoint where the problem happened and revert to the previous version if needed.
  • Collaboration: Version control is critical to allowing many people to work on the same project at once in a team environment. Each developer can be working on different areas of the code and their changes are merged seamlessly by VCS.
  • Backups and Recovery — With version control, your work gets backed up all the time. In the occurrence of alignment, data misfortune can prompt the loss of your whole association or potentially business work processes that are essentially urgent for general achievement.
  • Branching and Experimentation Version control systems create branches for testing. If it fails, delete the branch; if it works, merge it.
  • Accountability: VCS logs a history of changes made. This is useful for tracking who made what changes, holding people accountable for their work, and enabling developers on large teams to all work on the same codebase.
  • Saves time: Automating version handling reduces the scope of human error with VCS. Then developers can go back to writing codes and they no need to worry about managing the changes manually.

These days there are no excuses for not using version control to keep your software projects running smoothly, quickly, and effectively in a way that fosters collaboration.

So, What is git?

Git is a version control system that records changes to code over time. Breaking it down to basics, multi-user editing is when more than one person can work on the same project at once without stepping on each other's toes. Git tracks all the changes so that you can go back to any previous version of your code, merge other teammates' contributions, and work on a different feature using branches.

This is one of the core qualities that makes Git so powerful. That is, each developer has a full clone of the project history on their local machine. And you can continue working without any downtime even if the central server crashes. In modern software development, Git has become a cornerstone tool that is used in individual projects and large-scale collaborations alike.

Whether you are working on simple changes or trying to create complex functionalities, Git will keep your code in order and secure so that project management can be done correctly from its start to the end.

Famous Version Control System Platforms

Below are some of the popular version control system platforms widely used by developers for their project management and collaboration.

GitHub

The most used platform for keeping Git repositories is GitHub. It comes with a user-friendly UI and collaboration features like pull requests, code reviews, and issue trackers. GitHub is heavily used in open-source projects and has easy integration with other project development tools.

GitLab

GitLab: GitLab is an alternative to GitHub, a platform that provides Git repositories and also has CI/CD features. It is an end-to-end DevOps lifecycle: planning to monitoring. It is very versatile in its features, and it comes with both cloud-hosted options that you can purchase from GitLab or a self-hosted version as well.

Bitbucket

Bitbucket is owned by Atlassian; Bitbucket supports both Git and Mercurial repositories. It's most recognizable for its close relationship with other Atlassian products such as Jira and Confluence, which makes it the natural choice for teams using these tools. Pipelines for CI/CD are also available from Bitbucket, and you can have private repositories in the free tier as well.

SourceForge

SourceForge is one of the oldest platforms for hosting version control repositories. It is less popular than GitHub or GitLab. However, it remains a significant platform in the open-source community.

Azure DevOps

Azure DevOps from Microsoft has the services needed to develop, build, and test your work, essentially making it a one-stop shop for all development needs. High Level: A strong choice for Microsoft Azure enterprises.

AWS CodeCommit

AWS CodeCommit is a source control service provided by Amazon Web Services (AWS). It works with Git and is based on top of quite a few AWS services. Notably, it has been designed for scalability and security; this makes it a good option to consider if you are already on AWS.

Launchpad

Launchpad is a platform for hosting and managing open-source projects developed by Canonical (the creators of Ubuntu). It uses Git or Bazaar VCS and is frequently used by Ubuntu-related projects.

Perforce Helix Core

The Helix Core from Perforce is a VCS capable of managing large files and intricate projects. It’s used in industries like gaming or multimedia. It’s not as widely used for everyday software development projects as Git-based platforms. However, it is an alternative that developers turn to when dealing with large assets.

Each of these platforms will have different options and integrations to select based on your project’s needs. It also depends on how your team works together.

Wrapping Up

Remember: version control systems (VCS) are your best friend in modern software development. If you want to know whether projects will succeed or not, examine this data. From the individual developer to a big team, VCS sidesteps change-tracking issues and manages conflicts. It ensures that you have retained your work history. Developers understand there are different types of version control systems: local, centralized, or distributed. Using different tools, developers can select the right solution according to project needs. In essence, version control makes the development process more efficient. It protects the integrity and improvements of your codebase, a requisite for any productive software project.
