Rapidly Changing Dimensions A dimension attribute change is a rapidly changing feature. If we do not need to track changes, rapid quality is not a problem. If you need to follow the changes, then using the standard slowly changing amplitude technique can cause massive amplitude size inflation. The solution moves the attribute to its dimension, with a different foreign key. The new dimension is called a rapidly changing size.
A junk dimension fact table is a single table with the combination of attributes to avoid multiple foreign keys. Junk dimensions are created to manage foreign dimensions, that are created by rapidly changing dimensions.
