<h2>
What is a document database?
</h2>
<p>
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.<br />
<br />
For example here's a document:
<blockquote>
FirstName="Bob", Address="5 Oak St.", Hobby="sailing".
</blockquote>
Another document could be:
<blockquote>
FirstName="Jonathan", Address="15 Wanamassa Point Road", Children=("Michael,10",
"Jennifer,8", "Samantha,5", "Elena,2").
</blockquote>
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
(record) in this case. This system allows information to be added any time without
wasting storage space for "empty fields" as in relational databases.<br />
<br />
It is noteworthy here that using XML, YAML or JSON for information storage has advantages
similar to document oriented database. In these languages each record can have a
non-standard amount of information. Such information is properly called semi structured
data.<br />
<br />
Another advantage of document oriented databases is the ease of usage and programming
so that untrained business users, for example, can create applications and design
their own databases. Information can be added without worrying about the "record
size" and so programmers simply need to build an interface to allow the information
to be entered easily.
