Solution

A table is considered to be in the First Normal Form (1NF) when it meets the following conditions:

  1. Each table cell should contain a single value. This means that there are no repeating groups or arrays.

  2. Each record needs to be unique, i.e., there should be no duplicate rows in the table.

  3. Entries in a column (field) must be of the same kind. For example, in a column for age, all entries must be numeric.

  4. Each column must have a unique name.

  5. 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.
