Expert Data Modeling with Power BI by Soheil Bakhshi is a technical guide to designing Power BI semantic models that are reliable, understandable, secure, and efficient. Rather than treating reporting as a matter of importing tables and writing increasingly elaborate measures, it places data modeling at the center of analytical work. The book moves from foundational concerns, including data sources, table structures, and the flow of data through Power BI Desktop, toward more demanding modeling situations. These include relationship design, star schemas, changing dimensional data, security, dataflows, and composite models. Its purpose is practical: to help report developers turn business data from multiple systems into models that support accurate analysis and remain maintainable as requirements change. Bakhshi combines Power Query and DAX considerations with broader model-design decisions, without presenting either language as a substitute for sound architecture. The result is positioned as an advanced but structured resource for Power BI practitioners who need to understand why a model works, not merely how to make a visual return a result.
