A document-oriented database is a computer program designed for document-oriented applications. These systems may be implemented as a layer above a relational database or an object database.
As opposed to relational databases, document-based databases do not store data in tables with uniform sized fields for each record. Instead, each record is stored as a document that has certain characteristics. Any number of fields of any length can be added to a document. Fields can also contain multiple pieces of data.
For example here's a document:
FirstName="Bob", Address="5 Oak St.", Hobby="sailing".
Another document could be:
FirstName="Jonathan", Address="15 Wanamassa Point Road", Children=("Michael,10", "Jennifer,8", "Samantha,5", "Elena,2").
Notice that both documents have some similar information and some different - but unlike a relational database where each record would have the same set of fields and unused fields might be kept empty, there are no empty 'fields' in either document ...
