Answer / guest

Database normalization is the process of organizing the
fields and tables of a relational database to minimize
redundancy and dependency. Normalization usually involves
dividing large tables into smaller (and less redundant)
tables and defining relationships between them. The
objective is to isolate data so that additions, deletions,
and modifications of a field can be made in just one table
and then propagated through the rest of the database via the
defined relationships.
