In the context of relational databases, a tuple is one record (one row). The information in a database can be thought of as a spreadsheet, with columns (known as fields or attributes) representing different categories of information, and tuples (rows) representing all the information from each field associated with a single record.

HEY FRIEND UR ANSWER IS
In programming languages, such as Lisp, Python, Linda, and others, a tuple (pronounced TUH-pul) is an ordered set of values. The separator for each value is often a comma (depending on the rules of the particular language).
Common uses for the tuple as a data type are
(1) for passing a string of parameters from one program to another, and
(2) representing a set of value attributes in a relational database.
In some languages, tuples can be nested within other tuples within parentheses or brackets or other delimiters. Tuples can contain a mixture of other data types.
