Normalization<\/strong><\/p>\n<p>Normalization is the process of organizing data in a database to minimize redundancy and improve data integrity. It is a database design technique that helps to ensure that data is accurate, consistent, and easy to manage.<\/p>\n<p>There are three normal forms: first normal form (1NF), second normal form (2NF), and third normal form (3NF).<\/p>\n<p>1NF is the most basic level of normalization. It requires that each table have a primary key, which is a column or set of columns that uniquely identifies each row in the table.<\/p>\n<p>2NF requires that each table have a primary key and that all non-key columns depend on the primary key. This means that each column in the table must contain data that is related to the primary key.<\/p>\n<p>3NF requires that each table have a primary key and that all non-key columns are not transitively dependent on the primary key. This means that each column in the table must contain data that is directly related to the primary key and not indirectly related through another column.<\/p>\n<p>Normalization is an important part of <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> database design.
