If you're learning Power BI, focus first on data modeling rather than DAX or visuals. Data modeling means designing your table structure, choosing the right columns, setting the correct data granularity, and creating proper relationships between tables. A well-built model makes even complex problems simple to solve, reducing your need for complicated DAX formulas later.

Strong data modeling creates the foundation for all your reports and dashboards, making everything from basic visuals to advanced calculations work smoothly and efficiently.
