MIAMISBURG, Ohio, February 28, 2008 -- Teradata Corporation (NYSE: TDC), the global leader in enterprise data warehousing, announced today that Mizuho Bank, a leading financial services institution in Japan serving more than 25 million households, has completed implementation of Teradata Customer Management (CM) software application and multiple-terabyte Teradata Warehouse and database software. The CM application at Mizuho Bank is being used for event-based marketing (EBM), which enables one-to-one customer dialogue across multiple service channels.

Teradata EBM tools consist of software-based rules and triggers that detect, analyze and interpret customer interactions, which enable companies to provide timely and personalized attention to customers who may be in decision mode with regard to a product or service. Mizuho Bank commercial marketing activities include customer loans, personal credit cards, loyalty programs, and channel marketing-based services.

This is believed to be the first event-based marketing system of its kind deployed in Japan’s financial services industry. Mizuho is using its Teradata Warehouse-driven CM software to analyze multiple terabytes of detailed data linked to its millions of customers, and provide relevant and timely responses to better serve those customers.

“In banking, customer dialogue across channels is more complex – and more necessary than ever. Imagine holding millions of customer conversations every hour of every day that are timely, relevant, and driven by individual customer intelligence – across multiple channels,” said Sam Gragg, vice president of Teradata Customer Management Solutions Marketing. “We are very proud that our good customer Mizuho Bank has just completed its Teradata EBM implementation and is already reporting significant positive results. Companies across industries and the globe continue to adopt Teradata’s solution for event-based marketing because we have a decade of experience, proven methodologies and leading technology.”

Teradata's event-based solution library now contains more than 1,000 defined customer events that are data warehouse-driven and used across industries around the world. Customers include British Airways, Continental Airlines, DnBNor (Bank of Norway), Overstock.com, Royal Bank of Canada, Travelocity.com, Verizon Wireless, Westpac Bank, and in all, more than 50 percent of the top 10 global commercial and savings banks across the United States, Europe and Asia.

Teradata’s momentum continues in the global financial services industry as companies modernize and integrate critical information systems by replacing limited-use data appliances and data marts as well as slow, aging legacy data centers.
