About Database Schema Architect
The Database Schema Architect is a powerful visual tool designed for backend developers, database administrators, and software architects who need to design robust data models without manual SQL coding. This intuitive designer allows you to build tables, define columns, set data types, and establish relationships between entities with ease. Once your schema is perfect, you can instantly export the production-ready SQL DDL (Data Definition Language) for popular databases like PostgreSQL, MySQL, and SQLite. Whether you're planning a new feature or architecting an entire system, our schema designer helps you visualize your data structure clearly and ensures best practices in database modeling.
