Document-oriented database

Synonyms: Document database, Document oriented database, Document store, JSON database

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 with the use of the term NoSQL itself. Document databases contrast strongly with the traditional relational database (RDB). Relational databases generally store data in separate tables that are defined by the programmer, and a single object may be spread across several tables. Document databases store all information for a given object in a single instance in the database, and every stored object can be different from every other. This makes mapping objects into the database a simple task, normally eliminating anything similar to an object-relational mapping. This makes document stores attractive for programming web applications, which are subject to continual change in place, and where speed of deployment is an important issue.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. (Source: Wikipedia.org)
