In database normalization, what is the main goal?

• A. It is the process of removing all data from a database.
• B. It is the process of organizing data to reduce redundancy and improve integrity; uses normal forms.
• C. It is the method of translating data into multiple languages.
• D. It is the act of backing up databases to external storage.

Answer: (B)

The main idea being tested is organizing data so it isn’t repeated and its meaning stays correct by structuring it with normal forms. Normalization splits information into related tables, each with a clear purpose and primary key, to minimize redundant data and avoid inconsistencies when you insert, update, or delete. For example, keep customer details in a separate table from orders, so you don’t have to repeat a customer’s name and address for every order. This setup makes updates safer and keeps data consistent across the database. The other choices miss the point: removing all data isn’t about structure at all, translating data into multiple languages is a localization task, and backing up databases is a data protection activity, not a method for organizing data relationships.
