Best practice for importing SQL data to PBI
Hi luckygirl
Power BI works best when your data model is built using a Star Schema. This means importing dimension and fact tables separately, and connecting them using relationships (via primary/foreign keys) within Power BI. This approach is not only easier to understand and maintain logically, but also leads to better performance and more efficient data compression.
please refer to few excellent resources to help you understand why the Star Schema is preferred:
