SQL is one of the most important tools behind modern public health decision-making. In this episode, we explain what SQL (Structured Query Language) is, why it plays a critical role in public health, and how it’s used to manage and analyze large health datasets. You’ll learn how SQL supports disease surveillance, outbreak tracking, population health management, clinical research, and predictive analytics—and why practicing SQL is essential for working with real-world public health and data science workflows.
