# Database ERD

[View the Lucid database ERD diagram](https://lucid.app/lucidchart/c7e0d839-3011-4f3f-98c4-a8e256a68d0d/edit?viewport_loc=-1887%2C-3340%2C6909%2C3447%2C96OgJhKQsZJm\&invitationId=inv_28aad737-fed5-43c0-b0da-a677403ff4b6)

This page is the system-level entry point for the platform database entity relationship diagram.

Use this diagram when you need the overall database structure and relationships across the platform rather than a feature-specific slice.

The Lucid document is organized with a dedicated tab for each database schema so you can review each domain separately instead of working only from the full system view.
