A name–value pair, key–value pair, field–value pair, attribute–value pair, etc. is a fundamental data representation (see Data (computing)) in computing systems and applications.

Tuples

Designers often desire an open-ended data structure that allows for future extension without modifying existing code or data.

In such situations, all or part of the data model may be expressed as a collection of tuples, like this:

<attribute name, value>

Each element is an attribute–value pair.

Uniqueness of attribute names

Depending on the particular application and the implementation chosen by programmers, attribute names may or may not be unique.
