First Normal Form (1NF)

Description: In this video, we dive into the basics of database normalization and focus on the First Normal Form (1NF). Normalization is the process of organizing data into smaller, more stable table structures to reduce redundancy and improve flexibility. We’ll look at a real-world example of a company managing building projects and explore how a poorly designed table violates the rules of 1NF. Then, we’ll walk through the steps to restructure the data so that every column contains a single value, maintaining relationships while fixing design problems. By the end of this video, you’ll understand: ✅ What normalization is and why it matters ✅ The key requirements of First Normal Form ✅ How to spot multi-valued attributes and repeating groups ✅ How to use a composite key when needed This is Part 1 of our series on normalization. Stay tuned for Part 2, where we’ll move into Second Normal Form (2NF) and Third Normal Form (3NF). 🔔 Don’t forget to like, subscribe, and leave a comment with what you learned or any questions you may have! #DatabaseDesign #SQL #Normalization #FirstNormalForm
