What is Visual Schema Designer?

Designing a database schema visually is far more productive than writing DDL SQL by hand. DailyDevTools' Visual Database Designer lets you create tables, define columns with types and constraints, draw relationships (one-to-one, one-to-many, many-to-many), and generate the complete CREATE TABLE SQL for PostgreSQL, MySQL, or SQLite — all in an interactive drag-and-drop canvas.

How to use Visual Schema Designer

1. 1Click Add Table to create a new table and give it a name
2. 2Add columns by clicking the + button on each table: set name, data type, and constraints (PK, FK, NOT NULL, UNIQUE)
3. 3Draw relationships by dragging from a column to the primary key of another table
4. 4Click Export SQL to generate the complete DDL script with CREATE TABLE statements and foreign key constraints
