🧠 Section 4: Creating a Bubble Database

At the heart of every web app is data. Bubble’s built-in database allows you to manage it visually.

📊 Bubble Database Terminology:

• Data Type: Like a database table (e.g., User, Task, Product)
• Field: A column in the table (e.g., Name, Email, Price)
• Entry: A single row or record

Example: Product Marketplace Schema

⚙️ Section 5: Workflows – Adding App Logic

Bubble uses event-driven workflows to replace traditional JavaScript or backend logic.

🔁 Workflow Events:

• Element Trigger: Button clicked, input changed
• Page Load/Unload
• Custom Events
• Data Changes

🧩 Actions in Workflows:

• Create, modify, or delete a database thing
• Show/hide an element
• Navigate to another page
• Sign up/log in a user
• Run a custom event or API call

💡 Workflow Example:

Button "Add to Cart" is clicked → Add product to user's cart → Show popup → Navigate to cart page

📲 Section 6: User Authentication and Permissions

Bubble comes with native user management, making login systems incredibly simple.

✅ Authentication Features:

• User sign-up and login flows
• Password reset functionality
• Role-based access control
• “Current User” reference in workflows

🧾 API Integration Steps:

1. Enable API Connector
2. Add a new API with base URL
3. Define authentication (header, key, OAuth2)
4. Set up endpoints and test response
5. Use results in workflows or data sources

🧲 Section 8: Repeating Groups and Dynamic Content

Repeating Groups are how you display lists of data like blog posts, users, products.

Use Cases:

• Show search results
• List of recent articles
• A user’s order history
• Comments under a post

🎯 Tips for Repeating Groups:

• Bind the Type of Content (e.g., Product)
