ER Flow for Database Architects & Senior Engineers

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.

Benefits

Full multi-database support: PostgreSQL, MySQL, Oracle, SQL Server, and SQLite in a single tool
Stored procedures, triggers, and views are first-class objects on the ER canvas — not afterthoughts
Checkpoint-based versioning creates a complete audit trail of every schema decision and its rationale
SQL migration generation diffs any two checkpoints and produces precise ALTER TABLE statements
SQL import reverse-engineers production schemas for documentation, auditing, and refactoring work
Real-time collaboration enables distributed architecture review sessions without exporting diagrams to slides

How It Works

1

Import

Import your existing production schema via SQL dump. ER Flow reverse-engineers tables, indexes, foreign keys, views, and procedures.

2

Document

Organize tables into logical diagram views. Use grouping to separate domains — identity, billing, analytics, audit.

3

Design

Model schema changes visually. Add stored procedures, triggers, and views directly in the canvas alongside your tables.

4

Version

Save checkpoints at each design milestone. Compare any two checkpoints to generate a precise SQL migration diff.

5

Collaborate

Share diagram links with engineering teams for async review or use real-time collaboration for live architecture sessions.
