what is a tuple in database

In a database, a tuple is a fundamental concept in the relational model. It represents a single instance of a relation or table in the database and contains a set of values that correspond to the attributes of that relation. Essentially, a tuple is a row with linked data about a certain entity, and it is used to store inter-related data about a particular entity, such as a student, employee, or user. In the context of relational databases, a tuple is synonymous with a record or row, and it is the basic unit of data in a relational database management system (DBMS) .
