Final answer:
The network data model represents a many-to-many relationship, allowing complex links between entities.
Step-by-step explanation:
The network data model is known for representing a many-to-many relationship. In this model, a single entity can be linked to multiple entities on the other side, and those entities can also be linked to multiple entities, forming a complex web of relationships. This is in contrast to other relationships types, such as one-to-one, one-to-many, or many-to-one, which are more restrictive in terms of the links between entities. For example, in a network data model, a single customer might be linked to many orders, and at the same time, each order could be associated with many products, demonstrating a many-to-many relationship between customers, orders, and products.
