Yahoo! uses the MySQL database to power many of its web
properties. The first was Yahoo! Finance (
http://finance.yahoo.com.
), a popular web site that provides the full spectrum of
financial services and information. MySQL is behind Yahoo!
Finance's high-traffic area of news headlines, which is
aggregated from over 100 sources worldwide, as well as its
stock charts, insider trading, SEC filings, conference calls,
and earnings reports. Today, this is accomplished using
Yahoo!’s sophisticated publishing application called Jake
(Jointly Administered Knowledge Environment) based on
MySQL. In fact, Jake has become the enabling application
for MySQL usage across Yahoo! Properties worldwide.
