👋 Hi, It's Poom, and welcome to Datascale - your SQL productivity app. It's to help you organize your saved queries for your next data project 🌱. Thoughts? let’s chat on LinkedIn or Twitter 🎉


We present the way to draw your SQL queries as ER diagrams: a powerful tool for complex query understanding!

Why is this a game-changer?
  • Save time: No more manual diagramming! Generate accurate ER diagrams in seconds.

  • Understand someone else's code 😄: See join relationships clearly and easily.

  • Communicate your database schema: Share your ER diagrams with co-workers, ensuing everyone is on the same page.

How it works

We develop an algorithm to parse your SQL query and identify the tables, columns, and relationships involved. It then uses this information to automatically generate an ER diagram that is accurate and easy to understand.

    orders.order_id AS order_id,
FROM customers
LEFT JOIN orders
    ON customers.customer_id = orders.customer_id
LEFT JOIN shipments
    ON orders.order_id = shipments.order_id
WHERE orders.order_date >= "2024-01-25";

Ever stare at a mess of SQL, squinting to understand how your data is actually connected? You're not alone.
