Managing the Attributes Domain
The Attributes Domain provides a list of all the attributes available in the Compose model, as well as their data type. You can add, edit and delete attributes according to your data warehousing needs. The Attributes Domain also allows you to see which entities each attribute belongs to, as a single attribute may be present in several entities.
To manage the Attributes Domain
- From the drop-down menu in the top right of the Model panel, select Attributes Domain.
- Add, delete and edit attributes as describe in the table below.
