Document sources store data as paperwork (as against structured information with rows and columns). They have a programa that is adaptable and enables software programmers to evolve their database styles along with their applications.

A common apply case for record databases is cataloging products with thousands of characteristics like merchandise descriptions, features, dimensions, colours and supply.

They can be seen with JSON and other data interchange forms such as XML. Some likewise support a native SQL query terminology, others employ pre-defined opinions and the map/reduce pattern to parse the documents in to the appropriate structures for the purpose of processing.
