An attribute is non-unique information in a dataset (such as age or marital status) that can be compared and analyzed.

A Column or several columns can be combined in the Bunker during load to make a Category - this can then become a KEY or an ATTRIBUTE. Attributes are values retained in the dataset that are used to filter results and collect into anonymized statistics.

To see the accepted value(s) for each attribute within the Global Schema, see Global Schema attributes.
