ERD Tool

The ERD tool visualizes schema relationships so you can understand table structure without jumping between table lists, DDL, and foreign-key definitions.

What it shows

ERD views are designed to help you inspect:

• tables and columns
• primary-key and foreign-key relationships
• relationship direction
• related tables around a selected table
• larger schema maps when you need broader context

When to use it

Use ERD when you need to:

• onboard to an unfamiliar database
• review migration impact
• document relationships for teammates
• understand join paths before writing SQL
• spot missing or surprising relationships
