Database Normalization Concepts

The video tutorial explains database normalization, focusing on making databases more efficient by reducing redundancy and improving data organization. It covers the concept of normalization, starting with the inefficiencies in address field design and moving through identifying database problems like repeated fields. The tutorial introduces the first normal form and further steps to normalize a database, ultimately creating a relational database with multiple tables to enhance efficiency.

What is the primary goal of database normalization?

• To make databases more complex

• To reduce the number of tables

• To increase database efficiency

• To add more data to the database

Why is it inefficient to store an entire address in one field?

• It makes searching and querying difficult

• It takes up too much space

• It is more secure

• It is easier to update

What is a common issue with repeated fields in a database?

• They simplify data entry

• They waste space and can lead to errors

• They reduce the need for queries

• They make the database faster

How does introducing a customer ID help in database normalization?

• It allows for more data to be stored

• It makes the database more complex

• It reduces redundancy by avoiding repeated data

• It increases the number of tables

What is the benefit of creating a relational database with multiple tables?

• It reduces the number of queries needed

• It organizes data more efficiently

• It increases redundancy

• It makes the database harder to read
