When is a table in 3NF?

Database Management System

A table is in 3NF when it is in 2NF and it contains no transitive dependencies.

A table is in 3rd Normal Form (3NF) when it meets the following criteria:

  1. It is in 2nd Normal Form (2NF)
  2. There are no transitive dependencies in the table, which means that non-primary key columns are not dependent on other non-primary key columns.

A table in 3NF is considered to be free of transitive dependencies, and all the data in the table is directly tied to the primary key.
