robertman11: What database does Google use?

Google develops its own proprietary database and file system. Here could be a smart article that describes the origins of both :http://www.baselinemag.com/c/a/Infrastructure/How-Google-Works-1/

There was a documentary that explained it took a large portion of an entire nuclear facility to power their databases and servers. This is astounding, furthermore is the fact that this is not common knowledge.

I wonder what the ratio for revenue / jobs created would be for Google's overall presence.
It is very impressive.

The database Google use is No Relation Type with name BigTable. FaceBook uses Cassandra. If you try to develop a new Google here are some suggestions of Open Source Non Relation databases: MongoDB or CouchDB
