tuple
This term is primarily used in technical registers, specifically within mathematics, computer science, and database management. It describes a fixed-size collection of elements where the order of the items is significant. In programming, it often contrasts with a list or an array by being immutable, meaning its contents cannot be changed after creation.
In the context of relational databases, a tuple is the formal term for a row or record. While a table is a set of tuples, each individual tuple represents a single entity or instance of the data structure defined by the table's schema.
