Original: Power BI Finally Started Clicking(Schemas, Relationships & Joins)

Short summary

Power BI's foundation is the star schema: a central fact table linked to dimension tables via relationships (1:N, M:M with bridge tables). Understanding join types (inner, left, cross) prevents silent data loss and performance issues. Get the data model right and your reports, filters, and accuracy all follow.

  • •Star schema: one fact table (transactions) surrounded by dimension tables (context)
  • •Relationships: define primary/foreign keys and join types to prevent data loss
  • •Cross-filter direction and multiple relationships need careful management

Generated with AI, which can make mistakes.
