NYSE Euronext Achieves Large-Scale Data Management with Netezza

Netezza Corporation (NYSE Arca: NZ), the global leader in analytic
appliances, today announced that NYSE Euronext has chosen Netezza to
provide enhanced scalability for its growing data volumes. NYSE
Euronext is launching several enterprise-critical applications on
Netezza Performance Server(R) (NPS(R)) streaming analytic(TM)
appliances to enable improved organizational operations, investigate
potential trading anomalies and identify market trends. NYSE Euronext
joins a growing list of Netezza customers, including Catalina
Marketing and Epsilon, who have deployed 50 terabytes or more on the
NPS systems, validating the appliance approach for VLDB deployments.

NYSE Euronext operates the world´s largest and most liquid
exchange group and offers the most diverse array of financial products
and services, bringing together six cash equities exchanges in five
countries and six derivatives exchanges.

"With data volumes growing at 100 to 200 percent each year, we
worried about scalability and performance issues with our previous
data warehouse environment, which was also very complex and expensive
to maintain," said Brian Clark, chief architect and managing director
at NYSE Euronext. "Netezza´s simplicity allowed us to quickly
implement the NPS systems. With the incredible performance benefits
and improved time to market we are now realizing, we can easily keep
pace as data volumes spike. Netezza has simplified our entire data
warehouse environment."

"In the intense exchange market, millions of people around the
world rely on the ability to access up-to-date, accurate information,"
said Jit Saxena, chairman and CEO. "We are pleased that NYSE Euronext
has turned to Netezza to provide the performance, scalability and
reliability that it needs to satisfy its customers and ensure a fair
trading market."

Designed specifically for high-performance, terascale analytics,
the NPS system architecturally integrates a relational database,
server and storage into a single compact and power-efficient unit. The
system´s advantage comes from its patented Intelligent Query
Streaming(TM) design. Netezza has placed processing power next to the
data, so analysis occurs at the source at streaming speeds, delivering
an unprecedented 10-100 times the performance of traditional systems
at a fraction of the cost. Analyses that took days now take just
seconds. This means a dramatic increase in productivity across the
enterprise and faster time to value for business initiatives. Netezza
appliances are changing the way organizations leverage information,
creating a powerful analytic foundation for a new generation of
business analytics that improve strategic decision-making and drive
results.
