ERD View

The ERD (Entity-Relationship Diagram) view provides a visual representation of your collection's structure and relationships with other collections.

How to Access​

  1. Open Studio.
  2. Navigate to the Collections section.
  3. Click the ERD tab in the top navigation bar.

Diagram Elements​

The diagram displays your data model with the following elements:

Collection Nodes​

Each collection appears as a card showing:

  • Collection name at the top
  • List of fields with their data types
  • Field annotations (primary key, required, etc.)

Relationship Lines​

Lines between collections indicate relationships:

  • One side — Shown with a single line marker
  • Many side — Shown with a crow's foot (fork) marker

The line direction shows how collections relate (one-to-one, one-to-many, many-to-many).

Enum Nodes​

Separate nodes for enum types used in your schema are also displayed to show available options.
