Build a unified semantic layer across datasets with multi-dataset Topics in Amazon Quick

In this post, we walk through how multi-dataset Topics work, explain how the chat agent uses defined relationships to generate cross-dataset queries, and demonstrate an end-to-end implementation using a retail analytics scenario in Quick Sight.

Why this matters
Why now

The continuous evolution of AI in cloud services is driving the need for more intuitive and powerful data analysis tools, especially as data volumes and complexity increase.
