Documents encapsulate and encode data (or information) in some standard formats or

Documents are addressed in the database via a unique key that represents that document.
One of the other defining characteristics of a document-oriented database is that in addition to
the key lookup performed by a key-value store, the database also offers an API or query
language that retrieves documents based on their contents.
