Explanation

A star schema consists of a single central fact table containing quantitative and foreign key data, surrounded by multiple dimension tables that provide descriptive context. The name 'star' comes from the visual resemblance to a star when the schema is diagrammed, with the fact table at the center and dimension tables radiating outward like points.
