Day 50: Relational Database Normalization – From Functional Dependencies to Normal Form Decomposition

This lesson walks through relational database normalization using a messy enrollment table, showing how to derive functional dependencies, identify candidate keys, detect partial, transitive and BCNF violations, and systematically decompose the schema into student, major, course, teacher and enrollment tables while ensuring lossless joins and dependency preservation.
