Netezza Is Positioned In The Leaders’ Quadrant Of Leading Analyst Firm’s 2008 Data Warehouse Dbms Magic Quadrant

Netezza Position Based on the Company’s Completeness of Vision and Ability to Execute

Marlborough, MA — Netezza Corporation (NYSE Arca: NZ), the global leader in data warehouse and analytic appliances, today announced it has been positioned by Gartner, Inc. in the Leaders’ quadrant in the 2008 Data Warehouse Database Management Systems Magic Quadrant report released on December 23, 2008 and authored by Donald Feinberg and Mark A. Beyer.

The Gartner Magic Quadrant evaluates a vendor’s ability to execute and completeness of vision. According to the Gartner report, “The Leaders’ quadrant for data warehouse DBMSs contains those vendors that demonstrate the greatest degree of support for data warehouses of all sizes, with large numbers of concurrent users and management of mixed data warehousing workloads. These vendors lead the market in data warehousing by consistently demonstrating customer satisfaction and strong support, as well as longevity in the data warehouse DBMS market, with strong hardware alliances. Because of this track record, leaders also represent the lowest risk for successful data warehouse implementations. Additionally, the maturity of this market demands that leaders maintain a strong vision regarding the key points emerging during the past year: mixed workload management for end-user service-level satisfaction and data volume management.”

“We are pleased that Gartner has recognized Netezza and we believe the company has joined the ranks of the largest IT vendors in the world,” said Jim Baum, president and COO, Netezza. “In our opinion, our position in the Leaders’ quadrant not only demonstrates the growth of the data warehouse appliance market, but also marks Netezza’s entrance into the mainstream. We feel this honor affirms the company’s market leadership and dedication to delivering innovative, high-performance analytics across the enterprise.”

The Netezza data warehouse appliance is built specifically to analyze terabytes of detailed data significantly faster than existing data warehouse options, at a much lower total cost of ownership. It 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 its appliances to speed through processes that would occupy most data warehouse systems for hours or even days, thereby enabling dramatic increases in productivity across all organizations.

Netezza continues to receive significant praise from the industry. In 2008, Intelligent Enterprise named Netezza one of the “Intelligent Enterprise Dozen”—an elite list of 12 companies that will have the most impact on the technology community.
