Understanding Normalization in Databases

What is the primary goal of normalization in databases?

• To reduce redundancy and improve data integrity

• To increase redundancy for better data access

• To eliminate the need for primary keys

• To ensure data is stored multiple times

Which normal form requires that all data in a table be stored in atomic units?

• First Normal Form (1NF)

• Second Normal Form (2NF)

• Third Normal Form (3NF)

• Fourth Normal Form (4NF)

What is a primary key used for in database normalization?

• To uniquely identify table records

• To link data across different tables

• To decompose tables into smaller ones

• To store data in atomic units

What is a potential challenge of normalization in databases?

• Increased complexity in database queries

• Increased data redundancy

• Decreased data integrity

• Elimination of primary keys

What does the Third Normal Form (3NF) ensure in database normalization?

• Non-key attributes are not dependent on other non-key attributes

• All data is stored in atomic units

• All non-key attributes are fully functional dependent on the primary key

• Primary keys are used to uniquely identify records
