I am a beginner trying to understand the basic concepts of database's. I know several types of keys (Primary key, Foreign key, candidate key, super key, surrogate key.....etc). While learning about the degenerate dimension, I came across "dimension key".
In a data warehouse, a degenerate dimension is a dimension key in the fact table that does not have its own dimension table ----Ralph Kimball
Could someone please helps me understand the dimension key ?
