Define fields to structure the data that defines a single object. You can add fields to data types and specify the field type, such as Picklist, Boolean, or Text (single line). For example, to include a field that displays the confirmation number for an online order, you might add a Confirmation number field to the Purchase order data type, and then select Text (single line) as the field type.
