Frequently Asked Questions
Can I import existing SQL?
Coming soon! Currently, you can build your schema visually or by editing the JSON structure. We are working on a SQL DDL parser for Phase 13.5.
How does the Mermaid ER Diagram work?
Every time you add a table or define a relationship, our engine automatically generates the Mermaid.js ER Diagram syntax and renders it on the right-hand canvas.
Is the exported SQL production-ready?
