A tabular data card proposed for Babbage's Analytical Engine showing a key–value pair, in this instance a number and its base-ten logarithm. A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table.
It is a tuple (pair) that consists of a key–value pair, where the key is mapped to a value that is a set of columns. In analogy with relational databases, a standard column family is as a "table", each key–value pair being a "row". [1] Each column is a tuple consisting of a column name, a value, and a timestamp.

Example of a web form with name-value pairs. A name–value pair, also called an attribute–value pair, key–value pair, or field–value pair, is a fundamental data representation in computing systems and applications. Designers often desire an open-ended data structure that allows for future extension without modifying existing code or data.
In analogy with relational databases, a column family is as a "table", each key-value pair being a "row". Each column is a tuple consisting of a column name, a value, and a timestamp. In a relational database table, this data would be grouped together within a table with other non-related data. Two types of column families exist:
In this model, data is represented as a collection of key–value pairs, such that each possible key appears at most once in the collection. [ 26 ] [ 27 ] The key–value model is one of the simplest non-trivial data models, and richer data models are often implemented as an extension of it.
The arguments to this operation are the key and the value. Remove: remove a (key, value) pair from the collection, unmapping a given key from its value. The argument to this operation is the key. Lookup: find the value (if any) that is bound to a given key. The argument to this operation is the key, and the value is returned from the operation.
