DAYTON, OH — Teradata Corp. (NYSE: TDC, the analytic data platforms, marketing applications and services company, announced today that Groupon, a global leader of local commerce known for its website featuring discount coupons usable at local or national companies, has expanded its Teradata Data Appliance-based Data Warehouse to accommodate rapid business growth as well as a rising demand for deeper detail in analytics-driven intelligence.

Groupon’s expansion is an investment in Teradata that will provide immediate value along with the flexibility for future scalability. According to Groupon, the 500-terabyte Teradata system is delivering exceptional stability, reliability and performance.

“With our data volume rising at about fifteen percent annually, our expanded Teradata environment will enable Groupon to accelerate our marketing and reporting processes, enriching our data-driven insight across the business,” said Kris Srinivassan, vice president of enterprise data warehousing, Groupon. “Our users have found the Teradata system very useful from day one – and have been anxious to expand the platform as business demands grow and the need for more BI is stronger than ever. With more sophisticated and powerful analytics, we are empowered to better manage millions of queries a day, as well as the increasing number of customer engagement streams and cycles, notably in our Weekly Business Review, which is used by our leadership team to support the executive decision process.”

Teradata is growing its customer base in digital media and e-commerce markets with customers such as eBay, Netflix, Overstock, GoDaddy.com, Gilt Groupe, Electronic Arts, Rakuten (Japan’s largest online mall), Yahoo! Japan, Sabre/Travelocity and more.

“Web site business owners are facing new pressures to deliver to the bottom line—higher visit-to-conversion rates, higher online customer retention rates, lower abandonment, and larger online purchases,“ said David Grant, vice president, Teradata. “They need to create highly personalized, unique 1 to 1 experiences, but getting to remarkable site personalization requires more data faster – and the analytic speed to get intelligence delivered to the right person at the right time. This is Teradata’s sweet spot – and the reason why more ecommerce companies are turning to Teradata.”
