How to create a relational database in Bubble.io?

Understanding Bubble.io's Data Structure Bubble.io is a powerful no-code platform that allows you to create web applications without writing code. It provides a visual interface for building your database structure, which forms the backbone of your application. A relational database is a type of database that stores and provides access to data points that are related to one another. This guide will walk you through creating and managing a relational database in Bubble.io. Step-by-Step Guide to Creating a Relational Database in Bubble.io Step 1: Access the Data Tab

Log in to your Bubble.io account and open your application.
Find and click on the “Data” tab in the left-hand menu.

Step 2: Define Data Types

Click on the "Data Types" tab. This is where you will define the types of data your application will manage.
To create a new data type, use the input field at the bottom labeled "New type" and provide a name for your data type, such as "User," "Products," or "Orders."
Click "Create" to add the new data type.

Step 3: Add Fields to Data Types

Select a data type you have created by clicking on its name.
Under the "Data fields" section, you can add fields to this data type. For example, if the data type is "User," fields might include "First Name," "Last Name," "Email," etc.
Use the input labeled "Field name" to give a name to each field and select the appropriate field type from the dropdown menu (e.g., text, number, date, etc.).
For each field, click "Create" to add it to the data type.

Step 4: Establish Relationships Between Data Types

To create a relationship between two data types, add a new field in the data type that will reference another data type.
For example, if you want to link "Orders" to "Users," go to the "Orders" data type and add a new field named "User."
Set the field type to "User" (or whatever the name of the related data type is).
Click "Create" to add this relational field.
You can also make this field a list if an order can be related to multiple users by checking the "List" option.

Step 5: Populate Data and Test Relationships

Navigate to the "App Data" tab to manually enter some data for testing purposes.
Select a data type and click "New Entry" to add a data record.
Fill in the fields with appropriate values and make sure to link related data types correctly.
Click "Create" to add the record.

Step 6: Utilize Data in Your Application

Go to the "Design" tab to create UI elements that interact with your data.
Use elements like Repeating Groups to display lists of records from your database.
Set data sources and define conditions to filter the data displayed to users based on relationships.

Step 7: Manage and Optimize Database

Periodically review your data structure to ensure it meets the evolving needs of your application.
Optimize field types and relationships for performance, especially as your app scales.
