SQL Map
Drop PostgreSQL or IBM Db2 .sql files, or a .zip of them (a pg_dump, a db2look export, migrations, a schema), and get diagrams and a catalogue of everything in them: tables and how they reference each other, views, functions and what they read and write, triggers step by step, types, sequences, indexes, row security, grants and cron jobs. Everything runs in your browser. Your SQL is never uploaded.
