Terminology and Foundational Commands

Have a look at the commands and terminology used in Github:

• Repository - A collection of files and folders that are tracked by Git, a version control system.
• Clone - The process of creating a copy of a repository on the local machine.
• Commit - The process of saving changes to a repository. Each commit is accompanied by a message describing the changes made.
• Push - The process of uploading local changes to a remote repository.
• Pull - The process of downloading remote changes to a local repository.
• Branch - A parallel version of a repository. It is used to develop new features without affecting the main codebase.
• Merge - The process of bringing changes from one branch into another.
• Fork - A copy of a repository that belongs to a different user account.
• Pull Request - A request to merge changes from a fork or branch into the main repository.
• Issue - A tracking system for tasks, enhancements, and bugs within a repository.
• Collaborators - Users who are granted access to a repository to make changes, typically used in a team or organization.

Now that the fundamental of GitHub for Data Science is discussed, it is essential to know why GitHub is widely considered in Data Science. Although there are several reasons why data scientists might choose Data Science GitHub, some of the reasons are discussed below.

Why use GitHub for Data Science?

Let's understand why to use GitHub for Data Science:

Collaboration: GitHub for Data Science is designed to facilitate collaboration between multiple users. Data science projects often involve multiple team members, and Data Science GitHub makes it easy for them to work together on the same project simultaneously.

Reproducibility: Sharing code and data on GitHub allows others to reproduce data scientists' results. It makes their work more transparent and trustworthy.

Version Control: GitHub uses the version control system Git, which allows Data Scientists to keep track of different versions of their code and data. This makes it easy to roll back to a previous version if something goes wrong or to see how the project has evolved.

Sharing and Distribution: Data Scientists can share their work with others. Be it the code or the results, they can share it by creating a repository on Data Science GitHub that anyone can access. Also, if the project is open-sourced, it can be used and improved by others.

Community: GitHub for Data Science has a large and active community of users who can provide feedback, suggestions, and help with problems.

Integration: GitHub can be integrated with other tools and platforms commonly used in data science, such as Jupyter Notebooks, RStudio, and more, making it a convenient choice for data scientists.

Users can't optimize the benefits of GitHub for Data Science unless they know about the repository. Since the project details are saved in the repository, so here is the step-by-step process of creating and cloning a repository.

How to Create and Clone a Repository?  

Here is the process explaining creating and cloning the repository:

Creating a Repository

1. Go to the GitHub website and sign in to your account.
2. In the top-right corner of the page, there is a "+" button; click on it. It will open the drop-down menu. Select "New repository" from that menu.
3. Fill in the repository details. In the "Repository Name" field, enter a name for the repository. Optionally, users can also describe the repository and choose whether it should be public or private.
4. After filling in the details, click the "Create repository" button, and it's done.

Cloning a Repository

To clone a repository, it is mandatory to have Git installed on the computer. So, if it is not on the computer/laptop, it is recommended to download it from the official website.

1. Go to the GitHub website and find the repository to clone.
2. Click the "Clone or Download" button and copy the repository URL.
3. Open a terminal window on your computer and navigate to the directory to clone the repository, and use the command "git clone [repository URL]" (without the brackets) to clone the repository.
4. The cloning process may take a few minutes, depending on the size of the repository. Once done, the copy of the repository is now on the local machine.
5. To verify the clone, navigate to the cloned repository directory and check if the files are present.

Best Practices for Data Science GitHub

Here are some best practices for structuring a data science project using GitHub:

Also Read: Data Science vs Machine Learning

Create a clear project structure

Organizing the project's files and folders logically and consistently is recommended. For example, Data Scientists often have a data folder for raw and processed data, a notebooks folder for Jupyter Notebooks, and an src folder for the Python or R scripts. Also, using descriptive and consistent names for the files and folders is an effective practice. This makes it easy to understand what each file contains and where to find it.

Documenting the work

It is advisable to use a README file that provides an overview of the project, its goals, the data used, the dependencies, and how to run the code. A README file acts as a guide that provides users with a detailed description of the project in hand, and it can tell them how to use it and why it is functional.

Use branches

One can use branches to separate different project stages, such as development, testing, and production. This practice allows the user to experiment with new ideas without affecting the main codebase.

Use pull requests

Pull requests are an efficient feature of GitHub that allows users to review and merge changes from branches or forks into the main repository. They can also use this feature to collaborate with others and ensure that changes are properly tested and reviewed before merging.

Keep your repository up-to-date

It is recommended to regularly pull and merge changes from the main repository to keep the local copy up-to-date. This helps to avoid merge conflicts and ensures that the local copy is the same as the one on GitHub.

Use GitHub issues

Checking GitHub issues from time to time is another good practice to follow as it helps to track tasks, bugs, and feature requests. Moreover, it keeps the project organized and makes it easy to collaborate with others.
