Retailers in the U.S. provide 42 million jobs and add more than $2.6 trillion to the GDP each year. Nearly 99 percent are small businesses with fewer than 50 employees, and about 95 percent are single-location stores. Until recently, few had access to sophisticated retail analytics. Yet national mega-retailers have spent millions to build out big data analytics using and other software components, as well as thousands of commodity servers – a project far beyond the budget or capability of smaller retailers. Those national chains turn to analytics routinely to gather more customers and further enlarge their market share.
