Git Basics for Enterprise Developers – Core Concepts and Advantages

g4e stands for Git for Enterprise Developer; this series uses the g4e tag for easy reference. This is the second article in the basic Git tutorial for enterprise developers.

1. Basics:

Why use a version control system

Advantages of Git's distributed version control

Git installation and configuration

Initializing a Git repository (Repo)

Step 1 – Creating branches and saving code

Step 2 – Understanding Git history

Step 3 – Pull Request workflow

Git is currently the leading version control system and has become the industry standard. Below is a Stack Overflow survey chart showing Git’s dominant market share.

Git differs from centralized systems (SVN, TFVC, ClearCase) because it is distributed: each repository contains a full copy of the code, history, and branches. This enables offline work, flexible branching, and easy sharing when online.

Git’s flexibility and widespread adoption make it the default choice for teams. Most developers and graduates know how to use Git, and a rich ecosystem of resources exists for training and support. Almost all development tools and stacks integrate Git, and it runs on all major operating systems. Not using Git can hinder new hires and reduce productivity.

Basic Git Concepts

Commit

A commit records a snapshot of all file changes at a point in time. If files haven’t changed since the previous commit, Git reuses the previous snapshot. Each commit links to its predecessor, forming a chain of development history.

This linkage allows restoring previous versions, inspecting differences between commits, and identifying when and where changes occurred. Every commit has a unique identifier (commit id) generated by hashing its contents, enabling detection of modifications, loss, or corruption.

Branch

Unlike traditional systems, Git branches do not duplicate files; they simply point to different commit ids, allowing you to switch contexts without moving folders.

File and Commit States

Git files can be in three states: modified, staged, or committed. Changes first appear in the working directory (modified). Staging selects which changes will be included in the next commit. After staging, a commit records the snapshot, becoming part of the project history.

Advantages of Git

Parallel Development

Each developer has a full local copy, enabling simultaneous work on separate branches and offline operations.

Faster Release Cycle

Branching allows flexible development. The master branch holds stable release code, while feature branches contain ongoing work that merges back once complete, improving stability and release speed.

Built‑in Integration

Git is supported by virtually all IDEs and CI/CD tools, simplifying workflows and reducing the need for custom integration.

Strong Community Support

As an open‑source project, Git benefits from extensive documentation, tutorials, and community assistance.

Team Collaboration

Combined with tools like Visual Studio Team Services / Team Foundation Server, Git enables policy enforcement, automation, visibility, and traceability across teams.

Pull Requests

Pull requests facilitate code review, discussion, and quality assurance before merging changes into the main branch.

Branch Policies

Branch policies in VSTS/TFS enforce rules such as mandatory code reviews, required approvals, and successful build checks before allowing merges to protected branches.

Summary

At this point you should have a basic understanding of Git’s core mechanisms and its benefits. The next chapter will cover setting up a Git development environment.
