There is a 3-part structure of information within Stratum.Viewer
that includes dimensions,
hierarchies, and levels. Hierarchies
belong to dimensions and contain at least one level, which in turn contain
members. You can see an example of
this structure in view explorer. In the following example, there is a
Product Family hierarchy () with a Product Family level
(
) in the rows. The hierarchy belongs
to a Product Family dimension, which you can see when you access the Properties
window for the hierarchy.
