# Custom Big Object Fields

Custom fields store the data for your custom big object records.

## Custom Fields for Big Objects

Create custom fields to store information unique to your org. You can also create custom relationship fields to associate your big object with another object in Salesforce. Big objects support these field types:

- Lookup Relationship
- Date/Time
- Email
- Number
- Phone
- Text
- Text Area (Long)
- URL

To create an index for your big object, at least one custom field must be marked as required.

## Standard Fields for Big Objects

Currently, big objects don’t include standard fields.
