How to design a relational schema in Bubble.io?

Understanding the Basics of Relational Schema in Bubble.io Step 1: Define the Data Types (Tables)

Go to the Data tab in the Bubble editor.
Under the Data Types section, click on "Create a new type".
Name your new data type, which will act like a table in a relational database. Examples: Users, Orders, Products.

Step 2: Add Fields (Columns)

Select a data type you created.
Under the Fields section, click on "Create a new field".
Give your field a name and choose the type of data it will hold (e.g., text, number, date).
Repeat this process to define all necessary fields for each data type.

Step 3: Establish Relationships Between Data Types

Open one of your data types.
When creating a new field, set the field type to another data type to establish a relationship. For example, if you want to link Orders to Users, create a field in Orders named "User" and set its type to "User".
To create a one-to-many relationship, use List of: Data Type. For example, a User can have many Orders, you might create a list of Orders within the User data type.
For many-to-many relationships, create intermediate types. For example, if Users can have many Roles and Roles can have many Users, you might create a UserRoles data type that references both User and Role.

Step 4: Set Privacy Rules (Optional)

Navigate to the Privacy tab under Data.
Add a new privacy role by clicking "Add a new rule".
Define the conditions under which users can read, modify, or delete records for each data type.
This ensures that sensitive data remains secure and accessible only by intended users.

Step 5: Utilize Data in Your App

In your app's design tab, use different elements like repeating groups, input fields, and text elements to display and manipulate your data.
Configure these elements to pull data from your data types.
Make sure to use workflows to create, read, update, and delete data entries as per your app's requirements.

Step 6: Testing and Optimization

Test your data schema thoroughly by trying various CRUD (Create, Read, Update, Delete) operations.
Ensure all relationships are correctly set up and performing as expected.
Optimize the database by eliminating redundant data and ensuring efficient queries.

Best Practices

Consistently name your data types and fields for ease of understanding and maintenance.
Regularly back up your database.
Document your schema for future reference and onboarding new team members.
