Modify Fields in Your Atlas Entity-Relationship Diagram

In Atlas, go to the Data Explorer page for your project.

1. If it's not already displayed, select the organization that contains your project from the Organizations menu in the navigation bar.

2. If it's not already displayed, select your project from the Projects menu in the navigation bar.

3. In the sidebar, click Data Explorer under the Database heading.

   The Data Explorer displays.

Open the Data Modeling tab.

In the left sidebar, click Data Modeling.

Open your entity-relationship diagram.

From the Data Modeling tab, open your diagram.

Add a new field.

To add a new field, click the icon in the upper-right corner of one of your collection nodes. A new field appears in the collection node.

Once you add a field, you can edit the field's properties, including:

• Renaming the field.

• Changing the field's data type.

• Adding relationships.

Open the Field Properties side panel.

Click one of your fields in the diagram. The field side panel opens on the right side of the screen.

(Optional) Rename a field.

Under the Name section, specify a new name for your selected field.

(Optional) Change a field's data type.

In the Datatype drop-down menu, select the datatypes that you want to assign to the field. Because data in MongoDB has a flexible schema model, you can specify multiple data types for a field. If a field contains multiple data types, Atlas labels the field as (mixed) in the diagram.

(Optional) Delete a field.

In the side panel, click the icon.
