Question
What is 'normalization' in database
design?Solution
Normalization applies rules (normal forms: 1NF, 2NF, 3NF, BCNF, 4NF) to eliminate data redundancy, update anomalies (insertion, deletion, modification anomalies), and functional dependency issues. For example, storing a customer's branch name repeatedly in every transaction record is redundant — normalization separates this into a Branches table. Denormalization is sometimes done intentionally for read performance in data warehouses.
