[AccessD] Question

Hi Shamil:

I would suspect that Google uses an advanced custom designed OLAP database
engine where virtually ever field is indexed and weighted. I understand that
their databases reside on Linux boxes. A free (trial?) small version of the
Google engine/service can be acquired at
https://services.google.com/cobrand/free_trial

Does Google use mySQL?
