Learn Databricks in Under 2 Hours

Introduction

This tutorial is designed to guide you through the essential features of Databricks in under two hours. You'll learn how to work with data, utilize the SQL Editor and Notebooks, build dashboards, and integrate AI into your databases. Whether you're a beginner or looking to enhance your data analysis skills, this step-by-step guide will help you get hands-on experience with Databricks.

Step 1: Create a Databricks Free Account

• Visit the Databricks Free Tier signup page.
• Fill out the required information to create your account.
• Confirm your email address if prompted, and log in to your new Databricks account.

Step 2: Access Sample Data

• Go to the provided GitHub repository: Databricks Series Data.
• Download the data files you'll be using for your projects.
• Upload the data files into your Databricks workspace by navigating to the "Data" section and selecting "Upload".

Step 3: Navigate the Databricks Interface

• Familiarize yourself with the Databricks workspace layout:
  • Workspace: Where you will create notebooks and manage files.
  • Clusters: Manage and configure your computational resources.
  • Jobs: Schedule and manage automated tasks.
• Explore the SQL Editor by creating a new SQL query.

Step 4: Use SQL Editor

• Open the SQL Editor from your Databricks workspace.
• Write SQL queries to analyze your data. For example:

  SELECT * FROM your_table_name LIMIT 10;
  

• Execute your queries and review the results displayed in the output section.

Step 5: Create and Use Notebooks

• Create a new notebook by selecting "New" > "Notebook" in the workspace.
• Choose the language (Python, SQL, R, Scala) you want to use for your notebook.
• Write code or SQL queries in the cells and run them individually.
• Utilize markdown cells to document your analysis clearly.

Step 6: Build Dashboards

• After running analyses in your notebooks, create visualizations using the results.
• Click on the "Add Visualization" option after executing a query.
• Customize your visualizations (e.g., bar charts, line graphs) and save them.
• Navigate to the "Dashboards" section to compile your visualizations into a cohesive dashboard.

Step 7: Integrate AI Capabilities

• Explore Databricks' integrated AI tools, such as Machine Learning.
• Use libraries like MLlib for building machine learning models directly within Databricks notebooks.
• Implement a simple model, for instance, a linear regression, by importing necessary libraries and preparing your data.

Conclusion

By following these steps, you should have a solid foundation in using Databricks for data analysis, SQL querying, and dashboard creation, as well as a basic understanding of integrating AI capabilities.
