Welcome to Part 9 of our Database Design series! Today, we are diving into one of the most critical foundational rules for building solid databases: Functional Dependency.
In this lecture, we explore the cause-and-effect relationships within your data. You will learn how to identify "Determinants" and "Dependents," and understand how these functional dependencies act as the strict rules that govern table structure. Most importantly, I will show you step-by-step how to use these dependencies to accurately identify the Candidate Keys of any relation.
