Both 2NF and 3NF are concerned equally with all candidate keys of a table and not just any one key.

In this model, data is represented as a collection of key–value pairs, such that each possible key appears at most once in the collection. [ 26 ] [ 27 ] The key–value model is one of the simplest non-trivial data models, and richer data models are often implemented as an extension of it.
