Implementing Star and Snowflake Schemas in Healthcare Data Warehousing

Data warehouses integrate and analyze large databases to inform healthcare analytics decisions. Data warehouse architecture influences performance, scalability, and usability. Popular data warehousing schemas are Star and Snowflake. This paper compares healthcare data warehousing schemas. The star schema is used for query efficiency and simplicity in fast, simple contexts. Normalized snowflake schemas are more complex but space-efficient, making them helpful for intricate data relationships and exact reporting. This study compares various schemas in healthcare contexts, analyzes implementation tactics, and offers tips on optimizing their performance to support essential healthcare choices.
