How to do 1nf

Related questions
What is a normal form 1NF? The first normal form (1NF), like all normal forms, has specific requirements to be validated as 1NF. A table, as below, must be two dimensional with rows and columns, and each row must contain data that relates to something.
What is the difference between 1NF and 2NF? In 1NF, each table cell should contain only a single value, and each column should have a unique name. The first normal form helps to eliminate duplicate data and simplify queries. Second Normal Form (2NF): 2NF eliminates redundant data by requiring that each non-key attribute be dependent on the primary key.
How to normalize a table from 1NF to 3NF? To normalize a table from 1NF to 3NF, you need to normalize it to 2NF first then to 3NF. In the normalization process, you decompose a table into multiple tables that contain the same information as the original table. The normalization process usually removes many problems related to data modification.
What is the difference between 4NF and 5NF? Fourth Normal Form (4NF): 4NF is a further refinement of BCNF that ensures that a table does not contain any multi-valued dependencies. Fifth Normal Form (5NF): 5NF is the highest level of normalization and involves decomposing a table into smaller tables to remove data redundancy and improve data integrity.
