Git Dataflow

The following diagram shows an overview of the git data model and the basic commands used to transfer data between the storage locations.

Git Dataflow

Repository

The repo contains the files as well as the history of the changes made to those files. The history is a collection of snapshots at different points of time. The repository can be either local or remote. For git both types of repositories are equivalent.

Workspace

The workspace or worktree is the project on the local machine's filesystem. All the changes will remain in the working directory until they are added to the staging area or discarded.

Index

The index or also staging area is the place where the developer gathers and groups the changes before commit.

Practice

  1. Create a remote repository on GitHub
  2. Clone the remote repository
  3. Create a new file test.txt and add it to the index
  4. Add the file to the index
  5. Commit the file to the local repo
  6. Push the file to the remote repo
  7. Change the file test.txt on GitHub
  8. Pull the changes from the remote repo
  9. Check the contents of the file test.txt
