To ensure successful system rebuilding, Isetan Mitsukoshi System Solutions (IMS) selected a Teradata platform, as they did for the previous systems built originally more than ten years ago. IMS said its latest decision was based on the proven value of the Teradata platform, in particular its flexible data processing power, and the company's appreciation of the data warehousing expertise and track record of Teradata's past services work. The new systems are based on Teradata Active Enterprise Data Warehouse hardware and the Teradata Database  software. This takes advantage of the multi-generation hardware coexistence and high scalability to keep up with future growth in the volumes of data as well as new users of the system.

The primary purpose and use for the company's Teradata-driven analytical infrastructure is to provide support for merchandising and customer information analysis systems, while also integrating Mitsukoshi's many business applications. The newly updated data warehouse includes all data and analytical functionality from the previous Teradata system, however with newer components now offers greater operability and performance. Improvements to the system include a new user interface as well as enhanced processing power to manage increases in the volume of data and the number of users resulting from business integration. In particular, the new system can more quickly provide responses to a wider variety of complex queries issued from users, with most query responses answered in only ten to 30 seconds. Isetan and Mitsukoshi users have rated the new system highly.

"We are pleased that this enormous project has been completed successfully and is providing new and improved business value to the many users of the Teradata analytic infrastructure," said Yukihiko Yoshikawa, President of Teradata Japan.  "I extend congratulations to all cooperating members of the Isetan and Mitsukoshi organizations and my colleagues at Teradata."

First-line workers of the Isetan Mitsukoshi group make it a daily practice to analyze past data and review actual merchandise movement to take corrective action as needed.  

The user group manages merchandise at the SKU level with highly detailed information. The data thus obtained is processed in various ways on the Teradata-based analytic platform to optimize business performance. The merchandising and customer intelligence systems do not analyze data in a fixed and routine way but have the flexibility to allow each employee to do any specialized analysis he or she needs. This is one of the greatest benefits the new systems offer.

The merchandising information analysis system is used by 6,800 Isetan and Mitsukoshi employees daily, and processes about 260,000 queries a month. The IMS customer information analysis system is used by 2,000 employees and processes about 53,000 queries a month. Access concentrates heavily in the morning of every Monday to get weekend sales information for prompt action. They report that the power of Teradata can handle the large transaction quantities and delivers excellent performance in processing enormous volumes of data. The Isetan and Mitsukoshi groups continuously enhance the Teradata system to satisfy their performance requirements.
