The Importance of Normalization in Database Management and Optimization

Normalization

The gradual shift that makes a situation, idea, or behavior come to be more widely accepted or seen as “normal.” This term is sometimes used to describe how giving voice to prejudiced thoughts, which is generally regarded as unacceptable or outside the social norms of our polite, modern society, becomes more common and more accepted when authority figures such as business and political leaders do it. In the context of the article, though, the phrase “normalization of whiteness” refers to the way being white shifted from being a neutral fact to being the default, or “normal” race. That positioning relegating all non-white races to the category of “other,” which eventually became seen as “abnormal,” out of place, or less than. Over time, this creates the perception that there is something superior about white people. This phrase is used as a way to bring attention to one of the subtle processes that reinforces white privilege.

Normalization is a process of organizing data in a database to eliminate data redundancy and improve data integrity. It involves breaking down large tables into smaller, more specific tables and establishing relationships between them. The primary aim of normalization is to minimize data duplication and inconsistencies, which can lead to data anomalies and adversely impact data accuracy.

There are different levels or forms of normalization, including:

1. First Normal Form (1NF): This form requires that each table has a primary key, and every field must contain an atomic value. It means that each field or attribute in a table must hold a single value, rather than a list or a set of values.

2. Second Normal Form (2NF): In this form, all non-key attributes in a table must be fully dependent on the primary key. It means that all attributes in a table must be related and should not have any redundant data.

3. Third Normal Form (3NF): This form requires that there should be no transitive dependencies in a table. It means that a non-key attribute must not depend on another non-key attribute in the same table.

4. Fourth Normal Form (4NF): This form aims to eliminate multi-valued dependencies in a table.

There are higher forms of normalization beyond the fourth normal form, such as the fifth and sixth normal forms. However, they are rarely used in practice.

Normalization can help to improve database efficiency, reduce data duplication, and ensure data consistency and accuracy. However, it can also result in more complex database structures, which can make querying and updating data more difficult. Therefore, it is essential to strike a balance between normalization and usability.
