Relationships illustrate how entities interact with one another, capturing the nature and cardinality of these connections.

In an Entity-Relationship (E-R) diagram, an entity set is typically represented by a rectangle. Each rectangle contains the name of the entity set, which corresponds to a collection of similar entities. Attributes of the entities can be depicted as ovals connected to the rectangle, while relationships between different entity sets are shown using diamonds. This visual representation helps in understanding the structure and relationships within a database.
