This presentation briefly explains what version controlling is and where Git stands among other version control systems

1. The fast version control system

2. What is Git?

3. Git is a free and open source
distributed version control system
designed for speed and efficiency

4. What is Version Control?

5. Local Version Control Systems

6. Centralized Version Control Systems

7. Distributed Version Control Systems

8. Git Key Concepts

9. Storage : Snapshots, Not Delta Storage

10. Almost Every Operation is Local
● Uses the local database for it’s operations
● No network latency overhead
● Can commit locally and upload later when
you get a network connection

11. Data Integrity
● Each file and commit is checksummed for
integrity
● Uses SHA-1 hash
● This functionality is built into Git at the lowest
levels and is integral to its philosophy
● Impossible to change the contents of any file
or directory without Git knowing about it

12. Support for Non-linear Development
● Git encourages you to have multiple
branches (even thousands)
● A branch is just a pointer to a commit
● Enables you to do things like:
○ Frictionless Context Switching
○ Role-based codelines
○ Feature based workflow
○ Disposable experimentation

13. Git Only Adds Data
● Nearly all the actions in Git adds data to the
Git database
● Once you commit a snapshot into Git, it is
very difficult to lose
● Hence users can experiment without the
danger of screwing things up
