Key-Value Stores are simple databases, which use an associative array as a fundamental data model, wherein every key is linked with one value in a collection. The relationship is known as the key-value pair. 

Both values and keys can be anything right from simple objects to complicated compound objects. The key-value databases are partitionable and they enable horizontal scaling at a scale that other kinds of databases may not achieve.
