Understanding the Bubble.io Database: A Beginner's Guide

If you're new to building a Bubble app, welcome to our channel! Planet No Code is here to provide you with hundreds of Bubble tutorial videos, from beginner to advanced levels. You can find all of our videos on our website, planetnocode.com. In this beginner's guide, we will focus on understanding the Bubble database and how it works.

The Bubble Database

The Bubble platform is an excellent tool for creating web apps without coding. The database is a fundamental part of building a web app in Bubble. Think of it as a series of sheets in Excel or Google Sheets. Each sheet represents a data type in your app.

When you open Bubble, you will see different tabs on the left-hand side. The "Design" tab is where you create your user interface (UI), the "Workflows" tab is where you create your app's functionality, and we will focus on the "Data" tab in this guide.

Data Types and Fields

In Bubble, you can create different data types to represent different entities in your app. For example, let's say you want to create a data type called "Book." Bubble provides some built-in fields, such as "Who created it," "When it was created," "When it was modified," and a "Slug" for the URL.

You can also add additional fields to your data type. In the case of a book, you might want to add a "Title" field and an "Author" field. If you want to display books by author, you can create a separate data type called "Author" and establish a relationship between the two data types.

Creating and Editing Data

Once you've created your data types and fields, you can start adding data to your app's database. In the data tab, you can create new entries for your data types. For example, you can create a book entry and input the book's title and author.

It's important to note that any changes you make in the development version of your app do not automatically transfer to the live version. You can manually copy and restore the database, but be cautious to avoid overwriting important data.

Database Relationships and Privacy Rules

When structuring your data, you need to consider database relationships. For example, in our book example, the book has a relationship with the author, but the author does not have a direct link back to the book. This one-way relationship is essential for representing data on the app's pages.

Privacy rules are also crucial in Bubble's database. You can determine who can access and view certain data in your app. For example, if you want users to have their own personal library, you can set privacy rules to ensure that only they can see their books.

It's important to be mindful of who you give access to your Bubble app, as anyone with the right tools can potentially scrape data from your app. Setting appropriate privacy rules and considering user roles or team features can help protect sensitive data.


Understanding the Bubble database is essential for building powerful web apps without code. By creating data types, establishing relationships, and setting privacy rules, you can create a robust and secure app. If you have any questions or need further guidance, feel free to leave a comment, and we'll be happy to assist you.
