How is this called in a snowflake schema? I'm learning the basics of DWH modeling and I didn't find a name to refer to what I colored in red in the image below, i.e. a group of tables related to each other, with one of them being related to the fact table?



Does this have a name? (e.g. relationship branch?)
In Kimball terminology it would be a ﬁxed depth hierarchy. Using Inmon I think just a normalised dimension.
