Welcome to the Universal SQL Generator, a powerful web-based application that revolutionizes how database schemas are designed and implemented across multiple database platforms. This innovative tool provides a unified visual interface for creating comprehensive database structures that can be exported to MySQL, PostgreSQL, SQLite, SQL Server, and Oracle with platform-specific optimizations and proper syntax. By eliminating the need to learn the nuanced differences between database systems, this application empowers developers, database administrators, and students to focus on logical database design while automatically generating production-ready SQL code tailored to their chosen platform. Whether you're prototyping a new application, migrating between database systems, or learning database concepts, this tool bridges the gap between conceptual design and technical implementation.

Built entirely with HTML, CSS, and JavaScript, this self-contained application runs directly in your browser with no installations or backend dependencies required. The intuitive tabbed interface guides you through schema design, relationship mapping, and advanced configuration while providing real-time feedback through syntax-highlighted SQL previews. With features like database-specific data types, constraint management, sample templates, and multiple export options, the Universal SQL Generator transforms complex database engineering tasks into accessible visual workflows, making professional-grade database development available to users of all experience levels across any modern web browser.
