Question

Quizplus · Accepted Answer

The basic star schema includes facts, dimensions, attributes, and attribute hierarchies, with dimensions often referred to as "the heart of the star schema." Dimensions are the categorical information that is used to slice and dice the numerical facts, and they contain attributes and attribute hierarchies. Keys are a critical component of a dimension, but they are not a standalone component of the star schema. Relationships and cubes are not part of the basic star schema.
