How does data redundancy compare between a Star Schema and a Snowflake Schema?
- Both schemas have equal data redundancy
- Data redundancy is not applicable to either schema
- Snowflake Schema has higher data redundancy
- Star Schema has higher data redundancy
Snowflake Schema typically has higher data redundancy compared to a Star Schema. In a Snowflake Schema, data is normalized into multiple tables, resulting in more duplicate data across different tables. In contrast, a Star Schema denormalizes data into a single table for each dimension, reducing redundancy.
