A label provides a different means of representing an attribute. For related data, you can use labels in your logical data model to represent part or all of the attribute. For example, the Name attribute might have labels for Firstname and Lastname.
When selecting an attribute to include in a report, you can choose from any available labels for the attribute.
In the GoodData Portal, you can use labels as the display name for the related attribute.
