What is the difference between graph database and document database?

A graph databases provides immediate feedback on data relations, outpacing traditional relational databases. Like a graph database, a document store has the NoSQL technology handle all sorts of data types and perform quickly to filter this data.

What is the difference between key-value and document database?

The difference lies in the way the data is processed; in a key-value store, the data is considered to be inherently opaque to the database, whereas a document-oriented system relies on internal structure in the document in order to extract metadata that the database engine uses for further optimization.
