Version Control Systems

• Allows developers to work simultaneously
• Does not allow overwriting each other's changes
• Maintains a history of every version

Centralized Version Control System (CVCS)

Central server stores all files and enables team collaboration (Subversion)

Distributed Version Control System (DVCS)

Mirroring the full repository & offline usage (Git)

Git 

• master
• local repository
• fast
• offline (commit, branch)
• less management
• Not good with binary files
• No revision numbers
• Open source friendly

SVN

• trunk
• only working copy (specific revision)
• relatively slow
• needs to be online
• access permission handling
• no problem with binary files
• revision numbers

Basic Git Concepts

• git init (initialize the repo)
• git add training.md (add to staging area)
• git commit -m "Added training.md" (commit with message)
• git log (commit history of the repo)

Basic Git Concepts cont.

• git clone (create copy of remote repo on local)
• git pull (get latest version of remote repo)
• git push (send your latest version of local repo to remote)
