Which condition must be met for a table to be considered in the First Normal Form
Question
Which condition must be met for a table to be considered in the First Normal Form?
Solution
A table is considered to be in the First Normal Form (1NF) when it meets the following conditions:
-
Each table cell should contain a single value. This means that there are no repeating groups or arrays.
-
Each record needs to be unique, i.e., there should be no duplicate rows in the table.
-
Entries in a column (field) must be of the same kind. For example, in a column for age, all entries must be numeric.
-
Each column must have a unique name.
-
The order in which data is stored does not matter.
These rules ensure that there is no redundancy in the database, and data is organized in a logical and efficient manner.
