[dba-Tech] Graphics

Hello Jim,

I do not think it is an analysis tool.  From my quick read a week, I
understood it to be a plain old database, but instead of storing relations,
it stores nodes and edges instead of relations.

In addition to Stuarts link, I would urge any curious to look at the
diagram on Wikiapedia <http://en.wikipedia.org/wiki/Graph_database>

Funny thing, I never heard of Graph databases, or even the word Graph used
in this context yet two days ago I opened a software magazine I saw it
mentioned.

When those things happen, I always wonder did I see that word one hundred
times previously but always unconsciously ignored it.

Here are two sentences from Wikipedia.

"A *graph database* uses graph
structures<http://en.wikipedia.org/wiki/Graph_(data_structure)> with
nodes, edges, and properties to represent and store data. By definition, a
graph database <http://en.wikipedia.org/wiki/Database> is any storage
system<http://en.wikipedia.org/wiki/Storage_system> that
provides index-free adjacency. This means that every element contains a
direct pointer <http://en.wikipedia.org/wiki/Pointer_(computer_programming)> to
its adjacent element and no
indexlookups<http://en.wikipedia.org/wiki/Lookup> are
necessary."


"Graph databases are based on graph
theory<http://en.wikipedia.org/wiki/Graph_theory>.
Graph databases employ nodes, properties, and edges. Nodes are very similar
in nature to the objects that
object-oriented<http://en.wikipedia.org/wiki/Object-oriented>
programmers
will be familiar with."


So now we all know, it is that old reliable Graph Theroy.

Mark
