Скачать или смотреть Database Normalization Explained | Episode 3 – From ER Models to 3NF

In this episode, we explore how to move from an Entity-Relationship model to a well-structured relational schema. We explain what functional dependencies are and how to apply 1NF, 2NF, and 3NF to eliminate redundancy and update anomalies.

📌 What you’ll learn:
Mapping ER diagrams to relational tables
Functional dependencies and primary key rules
Step-by-step normalization (1NF → 2NF → 3NF)
Update anomalies and how normalization solves them
Design trade-offs and tips

🧠 Use Case Example: A messy table with multiple values per field gets transformed into a clean, normalized schema.
