Use the Schema Designer when planning new database structures, redesigning existing schemas, or collaborating with team members on data modeling decisions. It is essential for greenfield projects where the database architecture needs to be designed before implementation. Database architects use it to prototype and iterate on schema designs rapidly.
The Schema Designer supports visual design for PostgreSQL, MySQL, SQLite, SQL Server, and MongoDB. It generates CREATE TABLE statements and migration code specific to your chosen database system. The visual interface handles data types, constraints, indexes, and foreign key relationships for each supported platform.
The generated schema DDL follows best practices for each database system including proper data type selection, constraint definitions, and index creation. The output is syntactically correct and can be executed directly. However, always review performance implications of indexes and constraints for your specific workload.
All schema design and SQL generation happens locally in your browser. Your database architecture, table designs, and relationship models are never sent to any external server. This ensures your proprietary database structures remain completely private during the design process.
