PARISTeradata, a division of NCR Corporation (NYSE: NCR), today announced that the Leroy Merlin Group has deployed Teradata technology to create a worldwide decision-making environment based on an enterprise data warehouse. The group consists of six brand names in the do-it-yourself and home improvement markets (superstores, medium-sized stores and discount stores): Leroy Merlin, Bricocenter, Bricoman, Weldom, Aki and DomPro. The Leroy Merlin Group operates in France and eight other countries (Brazil, China, Greece, Italy, Poland, Portugal, Russia and Spain).

The Leroy Merlin Group selected Teradata to consolidate into a single enterprise data warehouse all of the disparate information-processing systems and data marts that were used by its various divisions. This multipurpose, comprehensive tool now combines information on all customers, purchases, sales, inventory and product reference numbers (by company, product and country). The data is drawn from the various operating systems and the different client interaction channels. In addition, it applies to all countries and all companies.

By implementing the Teradata warehouse, the Leroy Merlin Group is able to establish active enterprise intelligence for its strategic and operational needs. Information is updated in quasi-real time for a diverse group of users, including department managers, marketers, purchasers, sales directors, internal department employees and analysts. In all, the Teradata data warehouse currently receives 120,000 SQL queries per month for Leroy Merlin France.

Leroy Merlin Group chose Teradata due particularly to its high-volume data requirements. Currently, the group manages up to 5.4 terabytes of data, and this number is expected to grow. The Leroy Merlin Group is experiencing average annual revenue growth of 15 percent. Moreover, the system is now used by more than 1,000 employees in France and soon will be used by nearly 6,000 worldwide.

“With its robustness and flexibility, the Teradata enterprise data warehouse provides our on-site teams with efficient decision-making assistance, which has become absolutely necessary in an increasingly competitive sector,” explains Olivier Owczarczak, director of Decision-Making Information Systems of the Leroy Merlin Group. “Teradata helps us gain market share and actively contributes to achieving the group’s objective, which is to become number one for customer satisfaction in the world.”

Teradata Professional Services is handling the installation and integration of data analysis and restoration platforms.

“The Leroy Merlin Group has taken a new step forward by using Teradata enterprise data warehousing solutions,” says Eric Joulié, vice president for Teradata in Western Europe. “The group is able to provide better and more timely services to its customers.”
