Now come casinos. They take privacy very serious and next to that have the most amazing databases.

_MGM Mirage can sort its 6TB of data on Microsoft Corp. SQL Server databases to tell you which of its 9 million customers are poker players who also like onions on their hamburgers. “Whatever they do gets tracked and logged into the system,” Bonner said._

Just amazing.

_Unlike other companies, few casinos sell their customer data; it’s more valuable kept close. “We like to describe system criticality this way,” said Charette. “The systems are responsible for supporting $138,889 [in revenue] per hour.”_
