What kind of relationship does the following image represent?

Question

BlackTom AI · Accepted Answer

The question asks: 'What kind of relationship does the following image represent?' and provides answer options.

First, examine the diagram: on the left there is a single '1' and on the right there is a single '1', connected by a line. This setup indicates that each instance on the left corresponds to exactly one instance on the right, and vice versa.

Option 1: One-to-One. This matches the diagram’s structure, where each entity on each side pairs with exactly one entity on the opposite side. The presence of a single mapping line between the single entities reinforces this one-to-one pairing.

Option 2: One-to-Many. This would require a single instance on one side mapping to multiple instances on the other side (for example, 1 on the left linked to several on the right, or 1 on the right linked to many on the left). The diagram does not show multiple targets for a single source, so this is inconsistent with the image.

Option 3: Many-to-Many Relationships. This would be depicted by multiple connections forming a grid of mappings where multiple left-side entities connect to multiple right-side entities. The simple single line between single entities does not illustrate multiple pairings or cross-connections, so this option does not fit the diagram.

In summary, the visual shows a single left entity linked to a single right entity with a one-to-one correspondence, ruling out one-to-many and many-to-many interpretations.
