Catalina Marketing Expands Netezza Footprint; Analyzes 400 Billion Records Using Single Largest Data Warehouse Appliance Ever Purchased.

Leading Marketer Uses 100 Terabyte Data Warehouse Appliance to Provide Enhanced Marketing Services to Clients

FRAMINGHAM, Mass. -- Netezza, the global data warehouse appliance market leader, today announced that Catalina Marketing Corporation (NYSE: POS) has purchased the Netezza Performance Server[R] (NPS[R]) 10800 system to comprehensively analyze data from its database of more than 130 million shopper households. At 100 terabytes, the NPS 10800 is currently the single largest data warehouse appliance ever sold and will serve as Catalina's primary analytic data warehouse system.

Catalina Marketing, the global leader in behavior-based marketing solutions, provides consumer packaged goods (CPG) manufacturers and retailers the ability to execute targeted marketing programs specific to their customer base. These programs use shopper buying behaviors without compromising any personally identifiable information, and deliver incentives and messages via printers located at the point-of-sale of more than 21,000 retailers nationwide.

The NPS 10800's ability to handle extremely complex and mixed workloads will enable Catalina to streamline business operations and eliminate the use of less efficient systems. This will, in turn, allow Catalina to continue to analyze and develop one-to-one targeted marketing communications plans for its clients.

"Since information is at the core of Catalina, we are constantly looking for ways to improve how we use it to provide the best possible solutions for our clients," said Eric Williams, CIO of Catalina Marketing. "Because of the success we've had with the Netezza system, we have steadily scaled our deployment with larger workloads and data, as well as moved more swiftly and efficiently on all levels. With the NPS 10800 we will have the unique ability to further analyze, at the deepest level, a cross-section of purchasing data and provide those findings to our clients."

"We are proud to be able to provide Catalina Marketing with the high-performance, large-scale analytic engine it needs to meet the demands of its clients," said Jit Saxena, CEO and co-founder of Netezza. "Market-leading customers like Catalina are pushing the envelope with data warehouse appliances in terms of scale and innovation and continue to choose the NPS system over traditional data warehouse systems for its performance, value and ease of use. We are excited to reach this important industry milestone with the sale of our high-performance 100 terabyte data warehouse appliance."

Netezza announced yesterday the extension of its NPS 10000 Series product family http://www.netezza.com/releases/2006/release120406.htm, which now scales from a few hundred gigabytes to 100 terabytes to meet the demands of a broader range of enterprise data analytic needs. The company also continues to show significant momentum and growth, having just completed a record-breaking third quarter with the addition of many brand-name new customers.

The Netezza Performance Server system is the market-leading data warehouse appliance built specifically to analyze terabytes of detailed data 10 to 100 times faster than existing data warehouse options, at half the cost. The NPS system stores, filters and processes terabytes of records within a single unit, analyzing only the relevant information for each query. Netezza has placed the CPU power next to the data, allowing the NPS system to speed through processes that would occupy most data warehouse systems for hours, or even days, thereby enabling dramatic increases in productivity across the organization.

Customers who have recognized the benefits of Netezza's approach include Ahold, Amazon.com, Cingular Wireless, CNET Networks, Debenhams, Department of Veterans Affairs, Epsilon, Orange UK, Premier, Inc., Ryder System, Inc., Shoppers Drug Mart Corporation, The Carphone Warehouse and The TJX Companies.
