A professional-grade ER design tool with enterprise database support
Database architects need more than a drawing tool — they need a precise, version-controlled workspace for designing complex schemas across multiple RDBMS targets. ER Flow supports PostgreSQL, MySQL, Oracle, SQL Server, and SQLite, with stored procedures, triggers, views, checkpoint versioning, and SQL migration generation built in as first-class features.
Import your existing production schema via SQL dump. ER Flow reverse-engineers tables, indexes, foreign keys, views, and procedures.
Organize tables into logical diagram views. Use grouping to separate domains — identity, billing, analytics, audit.
Model schema changes visually. Add stored procedures, triggers, and views directly in the canvas alongside your tables.
Save checkpoints at each design milestone. Compare any two checkpoints to generate a precise SQL migration diff.
Share diagram links with engineering teams for async review or use real-time collaboration for live architecture sessions.
