Question 1

How to generate SQL from an ER diagram in DrawDB?

Accepted Answer

Design your database schema visually in DrawDB, then use the export feature to generate SQL scripts directly, including table creation and relationships. The tool supports both schema and migration script generation.

Question 2

DrawDB vs dbdiagram.io: which is better for free use?

Accepted Answer

DrawDB is completely free and open-source with optional self-hosting, while dbdiagram.io has a freemium model with limitations. DrawDB is ideal for privacy-focused users willing to manage their own setup, whereas dbdiagram.io offers more built-in features without setup.

Question 3

Can DrawDB handle large database schemas with many tables?

Accepted Answer

Yes, DrawDB is designed to be robust, but performance may depend on browser capabilities, and it's best for standard ERD tasks without advanced database features. For very complex schemas, testing in-browser is recommended.

Question 4

How to self-host DrawDB for private sharing?

Accepted Answer

Clone the repository, install dependencies with npm, and build the project. For sharing, set up the optional drawdb-server with environment variables as specified in the README's .env.sample file.

Question 5

Does DrawDB support PostgreSQL-specific syntax?

Accepted Answer

DrawDB generates standard SQL, but may not fully support all PostgreSQL-specific data types or extensions. Check the documentation or community discussions for any customizations or limitations.

Question 6

How to import existing SQL into DrawDB to create a diagram?

Accepted Answer

Use the import feature in DrawDB to parse existing SQL scripts and visualize them as ER diagrams, allowing for easy documentation and modification of database structures.
