In computing, the star schema (also called star-join schema, data cube, or multi-dimensional schema) is the simplest style of data warehouse schema. The star schema consists of one or more fact tables referencing any number of dimension tables. The star schema is an important special case of the snowflake schema, and is more effective for handling simpler queries.
Famous quotes containing the word star:
“The obvious parallels between Star Wars and The Wizard of Oz have frequently been noted: in both there is the orphan hero who is raised on a farm by an aunt and uncle and yearns to escape to adventure. Obi-wan Kenobi resembles the Wizard; the loyal, plucky little robot R2D2 is Toto; C3PO is the Tin Man; and Chewbacca is the Cowardly Lion. Darth Vader replaces the Wicked Witch: this is a patriarchy rather than a matriarchy.”
