Captions available
The idea
Database normalization structures a relational database to reduce data redundancy and improve data integrity — with each normal form applying to a table, not to the database whole.
In practice
An address recorded once instead of everywhere is the practice's visible result.
Where people slip
Table by table — the form is local, the benefit global.
