LAS VEGAS, October 14, 2008 -- Teradata Corporation (NYSE: TDC), the global leader in enterprise data warehousing and enterprise analytics, announced today that Sheetz, Inc., one of America's fastest-growing family-owned and -operated convenience store chains, has made a decision to select Teradata to build an enterprise data warehouse (EDW). The order also includes Teradata Warehouse Miner for advanced analytics, which enables data-mining technology from multiple vendors to be embedded and run within the Teradata enterprise data warehouse.

The convenience store chain, known for its award-winning food, innovative technology and excellent customer service, recognized the need for a powerful marketing technology solution that would scale and grow quickly with the business. The analytics software will support market basket analysis, affinity analysis and merchandising-related analysis. Teradata Professional Services will guide the data warehouse implementation.

"Teradata understands our unique information requirements and has a strong background in the retail business as well as in detailed analytical intelligence," said Jim Wenner, director of Information Technology, Sheetz.

Teradata was the first database vendor to integrate the data-mining process into the database engine, thereby leveraging the inherent parallelism and processing power of Teradata. Teradata Warehouse Miner 5.1, the latest version, integrates data mining within a centralized data warehouse, streamlining the data-mining process and making it possible to mine massive volumes of data with improved accuracy and speed.

"We are especially gratified to be selected by Sheetz because of its reputation for visionary levels of business leadership and meticulous execution of their corporate strategy using the most advanced technology," said Ed Dupee, vice president, global industry solutions, Teradata.
