Prompt to ERD

Prompt to ERD allows you to generate a complete Entity Relationship Diagram (ERD) by describing your database requirements in natural language.

Instead of manually creating tables and relationships, simply describe your application or business domain, and Qubase AI generates an initial database model that you can review and refine.

This feature helps accelerate the early stages of database design.

Before you begin

Before generating an ERD, ensure that you have:

Created a Workspace
Created a Project
Opened a Database Schema

[!NOTE] AI-generated database models should always be reviewed before use in production.

What can AI generate?

Depending on your prompt, Qubase AI can generate:

Tables
Columns
Primary Keys
Foreign Keys
Relationships
Suggested data types
Initial database structure

The generated model is automatically displayed on the ERD Canvas.

Example prompt

Example:


Create an e-commerce database.

Customers can place multiple orders.

Each order contains multiple products.

Products belong to categories.

Customers can submit product reviews.

Review and Edit

Generate an ERD

To generate an ERD:

Open AI Engineering.
Select Prompt to ERD.
Describe your database requirements.
Submit the prompt.
Review the generated database model.
Modify the ERD if necessary.
Save the Database Schema.

Reviewing the generated model

After generation, review:

Table names
Column names
Primary Keys
Foreign Keys
Relationships
Data types
Overall database structure

AI suggestions are intended to accelerate design, but they should always be verified.

Writing better prompts

Better prompts produce better database models.

Good prompts usually include:

Business domain
Main entities
Relationships
Business rules
Special requirements

Example:


Build a university management system.

Students enroll in multiple courses.

Teachers teach multiple courses.

Each course belongs to one department.

Students receive grades for each course.

Benefits

Prompt to ERD helps you:

Reduce manual database design
Create an initial database structure quickly
Explore different database designs
Learn database modeling concepts
Accelerate project development

Limitations

AI-generated schemas may require manual adjustments.

Examples include:

Business-specific rules
Naming conventions
Performance optimizations
Complex constraints

Always review the generated ERD before implementation.

Best practices

Write clear and specific prompts.
Include business rules whenever possible.
Review every generated relationship.
Validate the database model before generating SQL.
Refine the ERD after generation.

[!TIP] The more context you provide in your prompt, the more accurate and complete the generated ERD is likely to be.
