Foreign Keys

Foreign key diagram tool for relationship review.

ERD Studio helps reviewers understand how tables depend on each other. Use detailed relation mode for column-level inspection or simple relation mode for faster dependency review.

Use Cases

What this workflow is for.

01

Find which tables reference a selected table.

02

Review internal and external relationship highlights.

03

Bundle multiple relationships between the same tables for readability.

04

Use detail mode when a reviewer needs exact from-column and to-column paths.

Workflow

How ERD Studio supports it.

Inspect dependencies

Use relationship lines, count badges, highlights, and table selection to understand dependency paths.

Switch between detail and overview

Detailed relation mode supports implementation review while simple relation mode reduces visual noise.

Review DBML refs visually

DBML Ref definitions become visible relationships on the ERD canvas.
