D. Star schema In a star schema, dimension tables branch out from a central fact table, forming a star-like structure. Each dimension table represents a specific aspect or attribute of the data being analyzed, while the fact table contains the primary measurements or metrics. In a star schema, there are no sub-dimension tables; instead, each dimension table directly connects to the fact table.
