A document refers to an entry in the database (other databases MAY refer to the same concept as a row). A document has an ID (primary key in other databases), which is UNIQUE to the document and by which it can be located.

The document value contains the actual application data; for example, a product document may CONTAIN information about the price and DESCRIPTION. Documents are usually ( but not ALWAYS) stored as JSON on the server. Because JSON is a structured format, it can be subsequently searched and queried.
