Why Centralized Version Control Is a Must for Your Team

Centralized version

A version control tool helps development teams collaborate on projects, which is why even small teams need it. However, the larger a team gets, the more important it becomes. They allow you to easily track and manage changes to code, which will make it much easier to manage larger projects with a lot of contributors.

Three Types of Version Control Systems:

  1. Localized Version Control System:A local version control system is a local database located on your local computer, in which every file change is stored as a patch. Every update of files is listed in a patch.
  2. Centralized Distributed Version Control System:In Centralized Distributed Version Control System, all the changes in the files are tracked under the centralized server. The centralized server includes all the information of versioned files and a list of clients that check out from the central place (Example: SVN)
  3. Distributed Version Control System:In Distributed Version Control System, every developer has a repository. If Any server dies, any of the client repositories can be copied onto the server which helps restore the server (Example: Git)

An Introduction to SVN

SVN stands for Subversion. Apache Subversion or SVN is one of the most popular open-source, centralized version control systems. It comes under the Apache License. It is available for free over the internet. The subversion is an Apache product. We will first study the basic terminologies of SVN

Basic Terminologies

  • Repository:It is a central repository where all project files and directories like source code, documentation, and test cases are stored. As an individual, you can work on the files on your own device. It maintains all the history information of a particular artifact, User can go back and look into the log to see Who, When, and Why has changed.
  • SVN Checkout:It is the process of taking the project code or any files from the central repository to the local machine. Users can do modifications and can save all changes locally.
  • Commit:
    It is the process of saving all changes from the local machine to the Central Repository. During the commit, we provide meaningful commit messages for other users can easily understand.

To complete the installation of SVN, we need to install the SVN server and SVN client. Let’s see how to install the SVN server for windows.

How to Get Started with Command Line Subversion on Windows

In this part, we cover the basics of command line Subversion, from checking out a working copy to making your first changes and committing them back to the repository.

Steps:

  1. Open the command prompt
  2. In order to create your first repository, use the svnadmin create command followed by the path where you want the new repository and its name. For example,
    svnadmin create C:\Users\apurva\Documents\firstProject
    #

    #
  4. In the Documents folder some new files.Do not delete or modify any of these files.
    #

Advantages of SVN:

  • Quicky retrieve versions of code repository through the checkout process
  • More developers can work on the same code at the same time
