CARY, N.C., May 14, 2001 — Dialog, a leading provider of online-based information services and a subsidiary of The Thomson Corporation (TSE:TOC), won Grand Prize in the Database Scalability Program 2000, administered by Winter Corporation. The Dialog implementation consists of a proprietary DBMS, an Amdahl Corporation server, and an EMC storage solution.

The Database Scalability Program 2000 analyzes the characteristics of the world's largest databases and examines those supporting the world's largest workloads. These data repositories anchor e-commerce, business intelligence, supply-chain management, customer relationship management, resource management, and other business-critical applications.

"It is an honor to receive this award for Dialog," said Rick King, chief technology officer at Dialog. "Since the Dialog project started in 1968, we've been working with a specialized database system for "text" information used by many thousands of searchers around the world. Our storage environment contains a range of EMC enterprise Symmetrix storage processors. While the past challenges have been varied, sometimes difficult, and always interesting, we expect to encounter even higher hurdles and to continue to enjoy the work of clearing them."

Richard Winter, president of Winter Corporation, which administers the program, said, "By using the architectures, products, and practices best suited to their needs, Database Scalability Program winners are leading us into a new era of scalable business solutions.
