Tuple

Acronym: CQL

Within CQL, a tuple is the basic construct for representing structured values, with each tuple value consisting of a set of tuple elements, each of which has a name and a value. Tuples in CQL are analogous to records, or structs, in traditional programming languages, and rows in database programming languages. They are used within CQL to represent class instances from object-oriented data models, as well as XML or JSON instances.
