What kind of relationship is this figure an example of?Select one:a.Unaryb.One to allc.One to one

To determine the type of relationship depicted in the figure, let's briefly analyze the options provided:

1. Unary: A unary relationship involves a single entity, where a single entity is related to itself. An example of this would be an employee supervising other employees within the same entity.

2. One to All: This type of relationship suggests that one entity can be related to multiple instances of another entity, but it is not a standard term commonly used in database theory.

3. One to One: A one-to-one relationship occurs when one instance of an entity is related to exactly one instance of another entity.

Analysis

To identify which option fits best, observe how entities in the figure relate to each other:

• If an entity connects to multiple instances of another entity, it suggests a "One to All" relationship.
• If each instance is paired uniquely with another, it indicates a "One to One" relationship.
• If it relates to itself, it represents a 'Unary' relationship.

Final Answer

Without seeing the figure, I can't provide a definitive answer. However, you should analyze the connections between the entities based on the criteria outlined above to choose the correct option: a. Unary, b. One to all, or c. One to one.
