Which term refers to the association between entities in data modeling?

• A. Entity
• B. Relationship
• C. Attribute
• D. Identifier

Answer: (B)

The term that refers to the association between entities in data modeling is "Relationship." In the context of data modeling, relationships define how two or more entities relate to one another. They help to establish connections between different pieces of data, clarifying how entities interact and how they can be linked together in a database. This concept is fundamental in constructing relational databases, where each entity can potentially be associated with one or more entities through defined relationships, such as one-to-one, one-to-many, or many-to-many relationships. In contrast, "Entity" is a distinct object or concept that can have data stored about it, such as a customer or product. "Attribute" represents the properties or characteristics of an entity, indicating the data contained within that entity. "Identifier" typically refers to a unique attribute that distinguishes one entity from another, such as a primary key in a database. While these terms are all crucial in data modeling, it is the "Relationship" that specifically captures the concept of how entities are associated with each other.
