Final answer:
In the transition from conceptual design to logical design in database development, a relationship becomes a table. This table represents the defined relationships and interacts through foreign keys.
Step-by-step explanation:
A relationship in the conceptual design of a database becomes a table in the logical design. During the conceptual design, the focus is on defining the entities, relationships, and constraints of the model. When this transitions to logical design, the physical structure of the database is laid out. The entities become tables, attributes of those entities become columns within the tables, and the relationships determine how these tables interact with one another, often through foreign keys. Therefore, when a relationship defined in the conceptual model is implemented in a database's logical model, it materializes in the form of a table that stores the necessary data to represent that relationship.
