What steps must be completed to configure a one-to-many relationship between the Contact and Address entities?

To establish a one-to-many relationship between the Contact and Address entities, adding a Foreign Key field to the Address entity is essential. This Foreign Key references the Contact entity, effectively linking each address to a specific contact. This is crucial for enforcing the relationship, as it enables the Address entity to associate with one Contact while allowing a single Contact to be associated with multiple Addresses.

In addition to adding the Foreign Key, including an Array element in the Contact entity would further facilitate the relationship by allowing the storage of multiple addresses for a single contact. This approach mirrors real-world scenarios where one person (Contact) can have several places where they reside or correspond (Address). By implementing these components, the data model accurately reflects the one-to-many relationship through proper entity design.

Implementing a Foreign Key and an Array element together ensures that the data integrity is maintained, as it distinctly identifies which addresses belong to which contacts, allowing for efficient data manipulation and retrieval.
