What are some real-world examples of normalization in databases?

Normalization is the process of organizing data to reduce redundancy. A common example is a customer database where customer information is separated into different tables, like 'Customers' and 'Orders', to avoid duplication.

Can you explain how normalization helps in database design?

Normalization helps in database design by ensuring data integrity and reducing data anomalies. It allows for efficient data management and easier updates.

What are the different normal forms in normalization?

There are several normal forms, including First Normal Form (1NF), Second Normal Form (2NF), and Third Normal Form (3NF). Each form has specific rules to eliminate redundancy.

Can you give an example of a database that is not normalized?

Sure! A non-normalized database might have a single table that includes customer names, addresses, and their orders all in one row, leading to repeated data for customers with multiple orders.
