A key-value database is a type of non-relational database, also known as NoSQL database, that uses a simple key-value method to store data. It stores data as a collection of key-value pairs in which a key serves as a unique identifier. Both keys and values can be anything, ranging...
There are four main types of NoSQL databases: Key value: This is the most flexible type of NoSQL database because the application has complete control over what is stored in the value field without any restrictions. Document: Also referred to as document store or document-oriented databases, ...

Database types: key-value, document, columnar, and graph databases. Stores data depending on database type. Database type: tables of rows, grouped into relations. Uses Structured Query Language (SQL). Stores data as rows in tables; related data stored separately and joined for complex queries...
Another subset is key-value pair databases. Azure Table Storage, which I wrote about in my July 2010 Data Points column (msdn.microsoft.com/magazine/ff796231), is an example of a key-value pair NoSQL store. I should first address the definition of NoSQL. It’s become a bit of a ...
Column-oriented, where data is stored in cells grouped in a virtually unlimited number of columns rather than rows. Key-value stores, which use an associative array (also known as a dictionary or map) as their data model. This model represents data as a collection of key-value pairs. ...
Key-value databases, or key-value stores or tuple stores, use associative arrays, also called “dictionary” or “hash table”, with key-value pairs: A key is a unique identifier that retrieves its associated value. Simple integers or strings can be values, but JSON structures and other mor...
