Too much normalization is not necessarily a good thing. Sometimes, it can introduce unnecessary tables that can complicate updates and lookups.
For example, your user model might have several fields for their home address. Strictly speaking, you can normalize these fields into an address model. However, in many cases, it would be unnecessary to introduce an additional table to the database.
Rather than aiming for the most normalized design, carefully weigh each opportunity to normalize and consider the trade offs before refactoring.
