How can the foreign key relationship be established from the new entity to the owner entity?

To establish a foreign key relationship from the new entity to the owner entity, having the owner include an array of the new entity is a valid approach for representing a one-to-many relationship. This means that the owner entity can hold multiple instances of the new entity, thereby creating a connection where each instance of the new entity points back to its corresponding owner.

In this scenario, the array serves as a collection that maintains references to all associated new entities, effectively establishing the foreign key relationship. This is a common pattern in database design, where the owner is able to encompass multiple children (new entities) but each child belongs to only one parent (the owner).

This method promotes data integrity and facilitates efficient queries to retrieve related entities, reinforcing the relationship within the data model. By utilizing this structure, it can easily be accounted for in programming logic and database constraints, ensuring that valid relationships are maintained across the entities.
