Data modeling best practices for Amazon Quick Sight multi-dataset relationships

Data modeling best practices for Amazon Quick Sight multi-dataset relationships

Today, we are excited to announce Multi-Dataset Relationships in Amazon Quick Sight. This new capability lets you define logical relationships between Quick Sight datasets and perform runtime joins at query time. Instead of flattening tables ahead of time, you keep each table as its own Quick Sight dataset and declare how those datasets relate to one another inside a Quick Sight Topic.

Why this matters
