A company is designing a data warehouse and wants to ensure that query performance is optimized, even if it means the design will be a bit redundant. Which schema should they consider?
- Constellation Schema
- Galaxy Schema
- Snowflake Schema
- Star Schema
In a Snowflake Schema, the design intentionally allows for some level of data redundancy to optimize query performance. This schema structure involves normalized dimension tables, which can lead to better storage efficiency and reduced data update anomalies, even though it may have some level of redundancy.
