Final answer:

A simultaneous relationship among three entity types is called a many-to-many relationship, requiring a join table to manage the associations.

Step-by-step explanation:

A simultaneous relationship among the instances of three entity types in a database is most commonly referred to as a many-to-many (3) relationship. This implies that multiple instances of one entity can be associated with multiple instances of another entity, and vice versa, forming a complex network of associations. A many-to-many relationship often requires a join table or an association table to track the instances of the connections between the entities involved.
