QuickSight Multi-Dataset Modeling Patterns and Examples
AWS ML Blog · rss · 2026-07-08
This article takes a deep dive into specific data modeling patterns and SQL implementations for Amazon QuickSight multi-dataset relationships. The current version primarily employs an inner join mechanism.
Supported Modeling Patterns:
- Star Schema: A central fact table connects to multiple dimension tables. Suitable for fast queries and serves as the recommended foundational model.
- Snowflake Schema: Dimension tables are normalized into multi-level chains. Optimizes storage for large dimensions but increases query complexity.
- Galaxy/Constellation Schema: Multiple fact tables share consistent dimension tables, supporting cross-business process analysis (e.g., comparing sales and returns).
- Role-Playing Dimensions: The same dimension table (e.g., a date table) is referenced multiple times by the same fact table. This requires creating independent datasets based on the same source in QuickSight to map different roles (e.g., order date, ship date).
The article provides concrete table structure designs, use cases, and SQL query examples containing JOIN statements for each pattern.
