About Database Tools

Understand and document any database without installing anything. The Schema Explorer parses DDL from PostgreSQL, MySQL, MariaDB, Oracle, SQL Server, DB2 and SQLite, draws the table relationships as an interactive ER diagram, and lets you annotate tables and columns before exporting a data dictionary. All parsing happens entirely in your browser — your schema never leaves your device.
