Star vs Snowflake Schema

Star and snowflake schemas are methods used to organize data in a relational database for analytics and reporting. A star schema features a central fact table connected directly to multiple denormalized dimension tables, creating a structure that resembles a star and prioritizing query performance. A snowflake schema is an extension of the star schema where dimension tables are normalized into multiple related tables, which reduces data redundancy but increases the complexity of joins required to retrieve information.
