MODERN SQL FOR BUSINESS INTELLIGENCE: The Definitive Guide to Building Dashboards, Driving Analysis, and Delivering Insights with Microsoft Power BI and Server.

Many BI analysts and SQL developers face a critical gap: they know the power of Power BI and they know the language of SQL, but making them work together in perfect harmony is a challenge. The result is often slow reports, complex maintenance, and a constant struggle to deliver truly deep, actionable analysis. This is the single biggest barrier to becoming a high-impact BI professional.
