Noun

tuple (plural tuples)

1. (set theory) A finite sequence of terms.

   A tuple is not merely a totally-ordered set because the same element can appear more than once in a tuple: for example, (a,b,a) qualifies as a 3-tuple whereas it would not qualify as a totally-ordered set (of cardinality 3), because the set would be {a,b} where $a \le b$ and $b \le a$ so that a = b; i.e., it would actually be a one-element set, {a}, not even just two-element.

2. (computing) A single row in a relational database.
3. (computing) A set of comma-separated values passed to a program or operating system as a parameter to a function call.

Synonyms

• (finite sequence of terms): n-tuple (when the sequence contains n terms), ordered pair (when the sequence contains exactly two terms), triple or triplet (when the sequence contains exactly three terms)

Related terms
