Tesco’s international momentum is expected to continue. A recent report from the Institute of Grocery Distribution, a British food industry group, forecasts Tesco will continue to grow at an average of 11% annually through 2012, enabling it to overtake France’s Carrefour to become the world’s second-largest retailer by 2012. 5 Analysts say that Tesco’s big advantage over major international rivals is its unrivaled ability to manage vast reams of data and translate that knowledge into sales. While data crunching may sound dull, it has given Tesco two major advantages: an unmatched ability to operate multiple retail formats — ranging in size from convenience stores to hypermarkets — and the market knowledge to offer what many analysts say is the best and broadest range of house brands from any retailer. 6 Tesco uses information gleaned from Dunnhumby, a British data mining firm of which it has majority control, to manage every aspect of its business, from creating new shop formats to arranging store layouts to developing private-label products and targeted sales promotions. In 2003, U.S. supermarket chain Kroger copied Tesco’s example, setting up a joint venture with Dunnhumby in the U.S. Since then, Dunnhumby also has signed deals with a number of other U.S. retailers including Home Depot, Best Buy, and Macy’s. 请阅读以上3个段落,并回答以下问题:
