How can multivalued attributes be handled within the databse design?

Multivalued attributes can be handled in database design by creating a separate table to store the values related to that attribute, establishing a one-to-many relationship with the original table. This new table contains a foreign key that links back to the primary key of the original table, allowing multiple values to be associated with a single record. Additionally, normalization techniques can be applied to ensure efficient data organization and retrieval. By doing this, the database maintains integrity and avoids redundancy.
