Explain the concept of cascading updates in database normalization.

Cascading updates in database normalization refer to the automatic propagation of changes made to a primary key value to all related foreign key values in other tables. When a primary key value is updated in a table, the cascading update feature ensures that all corresponding foreign key values in related tables are also updated accordingly. This helps maintain data integrity and consistency throughout the database by ensuring that all related records are updated consistently.
