    NoSQL Database Types ???

    Document databases pair each key with a complex data structure known as a document. Documents can contain many different key-value pairs, or key-array pairs, or even nested documents.

    Graph stores are used to store information about networks, such as social connections. Graph stores include Neo4J and HyperGraphDB.

    Key-value stores are the simplest NoSQL databases. Every single item in the database is stored as an attribute name (or “key”), together with its value. Examples of key-value stores are Riak and Voldemort. Some key-value stores, such as Redis, allow each value to have a type, such as “integer”, which adds functionality.

    Wide-column stores such as Cassandra and HBase are optimized for queries over large datasets, and store columns of data together, instead of rows.
