SQL remains one of the most powerful tools in modern data analytics—and this book helps you use it not just to write queries, but to deliver insights.
SQL for Data Analytics, Fourth Edition takes you beyond basic SQL syntax and teaches you how to analyze real-world data with confidence. Whether you're a beginner aiming to understand production data or a professional seeking to upgrade your analytics toolkit, this book gives you the skills to turn data into actionable outcomes.

You'll begin by learning how to create and manage structured databases, before diving into data retrieval, transformation, and summarization. From there, you’ll tackle more complex tasks: window functions, statistical operations, and analysis of geospatial, time-series, and text data.
With hands-on exercises, case studies, and detailed guidance, this book prepares you to apply SQL in everyday business contexts—whether you're cleaning data, building dashboards, or presenting insights to stakeholders.
