A document-oriented database , or document store , is a computer program designed for storing, retrieving and managing document-oriented information, also known as semi-structured data. Document-oriented databases are one of the main categories of NoSQL databases, and the popularity of the term "document-oriented database" has grown [2] with the use of the term NoSQL itself. XML databases are a subclass of document-oriented databases that are optimized to work with XML documents. Graph databases are similar, but add another layer, the relationship , which allows them to link documents for rapid traversal. Document-oriented databases are inherently a subclass of the key-value store , another NoSQL database concept. The difference lies in the way the data are processed; in a key-value store, the data are 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.
