Which of the following schemas is characterized by normalized dimensions?

The snowflake schema is distinguished by its normalized dimensions. In this schema design, the dimensional tables are structured to eliminate redundancy by breaking them down into multiple related tables. Each dimension is organized into a hierarchy, allowing for a more detailed and granular representation of data. This normalization helps ensure data integrity and reduces storage requirements, as common attributes can be stored in separate tables and referenced through relationships.

This structure contrasts with the star schema, where dimensions are typically denormalized, resulting in a flatter structure with fewer tables. The flat schema typically involves a single table design where all data is stored in one place, lacking any normalization. The hybrid schema combines aspects of both star and snowflake schemas, utilizing both normalized and denormalized data structures, but does not specifically focus on normalized dimensions like the snowflake does.
