  2. Key–value database - Wikipedia

    en.wikipedia.org/wiki/Keyvalue_database

    A tabular data card proposed for Babbage's Analytical Engine showing a keyvalue pair, in this instance a number and its base-ten logarithm. A keyvalue database, or keyvalue 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.

  3. Standard column family - Wikipedia

    en.wikipedia.org/wiki/Standard_column_family

    It is a tuple (pair) that consists of a keyvalue 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 keyvalue pair being a "row". [1] Each column is a tuple consisting of a column name, a value, and a timestamp. [2]

  4. Name–value pair - Wikipedia

    en.wikipedia.org/wiki/Name–value_pair

    Example of a web form with name-value pairs. A name–value pair, also called an attribute–value pair, keyvalue 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.

    Apache Ignite is an in-memory computing platform that is durable, strongly consistent, and highly available with powerful SQL, key-value and processing APIs. With full SQL support, one of the main use cases for Apache Ignite is the in-memory database which scales horizontally and provides ACID transactions. ArangoDB: ArangoDB GmbH 2011

  7. Distributed hash table - Wikipedia

    en.wikipedia.org/wiki/Distributed_hash_table

    For example, key k could be the node ID and associated data could describe how to contact this node. This allows publication-of-presence information and often used in IM applications, etc. In the simplest case, ID is just a random number that is directly used as key k (so in a 160-bit DHT ID will be a 160-bit number, usually randomly chosen ...

  8. Column family - Wikipedia

    en.wikipedia.org/wiki/Column_family

    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:

  9. Association list - Wikipedia

    en.wikipedia.org/wiki/Association_list

    To test whether a key is associated with a value in a given association list, search the list starting at its first node and continuing either until a node containing the key has been found or until the search reaches the end of the list (in which case the key is not present). To add a new keyvalue pair to an association list, create a new ...
