Normalization

Normalization is a process of organizing data in a database to reduce redundancy and dependency. It involves breaking down a table into smaller tables and defining relationships between them. The main goal of normalization is to eliminate data redundancy and improve data integrity. Normalization is achieved by applying a set of rules called normal forms. There are several normal forms, including first normal form (1NF), second normal form (2NF), third normal form (3NF), and so on. Each normal form has its own set of rules that must be followed to achieve that level of normalization. Normalization is an important concept in data science and artificial intelligence because it helps to ensure that data is consistent and accurate, which is essential for making informed decisions based on data.
