MIAMISBURG, Ohio, and TOKYO, Japan, 8/5/2008 -- Teradata Corporation (NYSE: TDC), the global leader in enterprise data warehousing, announced today that Tokyo-based Isetan Mitsukoshi System Solutions Limited, which provides a central information system to Isetan Company, Ltd., a leading presence in the international retailing industry, has expanded its Teradata strategic information platform.

The Teradata strategic information platform is used by Isetan to analyze enormous volumes of merchandise and customer data, providing business insight and marketing intelligence for many retail business decision makers and analysts at Isetan. Query performance and scalability are important to Isetan and are considered differentiating attributes for the Teradata business intelligence platform. The Teradata system has been in use at Isetan for a decade. Over the years, it has been expanded to support increasing numbers of business users and growing volumes of data. The latest expansion will be launched this month.

Isetan is highly regarded for its unparalleled abilities to analyze and utilize information to improve business performance and better serve its millions of customers in many countries. Isetan's analytical capabilities are particularly strong in merchandising and customer intelligence, and together represent vital management tools that support Isetan's growing international business. The Teradata platform provides enterprise-class visibility to detailed information such as sales, transaction and inventory data.

Specifically, Teradata provides the analytical environment for the Isetan I-Card, an in-house credit card program and part of an intense focus on customer relationship-building initiatives. Detailed point-of-sale data is fed to the Teradata system when customers use the Isetan I-card, identifying each customer, purchase, date and store or transaction channel. This pool of information, protected by powerful data security tools and access policies, is transformed to actionable intelligence so that Isetan's marketers can contact individual customers with the most relevant and timely offers.

Isetan is expected to grow further under the guidance and leadership of Isetan Mitsukoshi Holdings Ltd. The retailer has innovative plans to integrate its enormous intelligence systems with other department store chains. The expansion of its present Teradata information platform is an important effort at the core of this project.

"Isetan is making a strong intelligence platform even stronger," said Ed Dupee, vice president, Teradata global retail industry solutions. "Teradata appreciates the confidence Isetan has placed in our people and our technology."
