Hello @Nobuhiko!

Databricks lab materials mainly consist of interactive notebooks with step-by-step instructions, code, and explanations.

• Notebooks are the main content for step-by-step exercises and instructions, accessed directly within the lab workspace.
• All required raw data is already provided and accessible in your lab environment.
• Key variables (like “DA”) and settings are pre-configured, you don’t need to set up anything manually.
• System scripts automatically set up and configure your environment in the background, you typically won’t interact with these directly.

In all, everything is preloaded, isolated to your lab session, and cleaned up when your time ends. Lab materials are comprehensive and ready-to-use, so you can focus entirely on learning and hands-on practice.
