Final answer:
A set of data that describes a single instance of the entity represented by a relation is known as a tuple.
Step-by-step explanation:
A set of data that describes a single instance of the entity represented by a relation is known as a tuple.
In the context of databases, a tuple is a row in a table that contains information about a specific entity. For example, in a student database, each row (tuple) could represent a single student with information such as their name, age, and grade level.
Tuples are important because they allow us to organize and store data in a structured manner, making it easier to manipulate and retrieve information efficiently.
A set of data that describes a single instance of the entity represented by a relation is known as a tuplet or row in database terminology. In the context of databases, data represents observations collected to form a database, which can be used to test hypotheses or queries.
Each row in a table corresponds to one instance of the type described by the relation, and each column represents a different attribute of that instance.
