The values of the attributes in a database describe a particular __________.

Concept

In an entity–relationship model, an entity is a distinguishable real-world object or concept about which data is stored. Attributes name its properties, while a concrete set of attribute values characterizes one particular entity instance.

Application

Suppose Student is an entity type with attributes RollNumber, Name, and Programme. The values {105, Asha, B.Tech} characterize one particular student entity; a relational implementation may store that set of values in one tuple.

Contrast

• Entity names the modeled object or one of its instances; attribute values characterize that instance.

• Tuple names a row in a relation; it is the relational structure that contains one value for each attribute.

• Field names one data item associated with a single attribute in a record or a column in common database usage.

• View names a virtual relation derived from a query over one or more relations.

Result

Therefore, the attribute values describe a particular entity instance, so the offered value is Entity.
