What is Database Normalization and Why is it Important in Database Design?

Database normalization is the process of organizing a database to reduce redundancy and improve data consistency. It involves breaking down a database into smaller, related tables and establishing relationships between them. This helps in minimizing data duplication and ensures that information is stored efficiently.

Database normalization is important in database design as it helps in:

• 1. Eliminating data redundancy: By organizing data into separate tables and linking them through relationships, redundant data is minimized, leading to a more efficient database.
• 2. Improving data integrity: Normalization ensures that the data is stored consistently and accurately, reducing the risk of data inconsistencies.
• 3. Enhancing data consistency: With normalized databases, updates and modifications only need to be made in one place, improving data integrity and reducing errors.

In conclusion, database normalization is essential in database design as it promotes efficiency, data integrity, and consistency, ultimately leading to a well-structured and optimized database.
