What is Sql Designer?

SQL Designer is a free, browser-based entity relationship diagram (ERD) tool that lets developers visually model relational database schemas. Create tables, add columns with real database types, set constraints, and draw foreign key relationships using crow's foot notation. Export complete CREATE TABLE scripts for MySQL, PostgreSQL, SQLite, Oracle, SQL Server, or MS Access—or import existing SQL to visualize and edit instantly. No installation, login wall, or credit card required.
