So what are the facts? In 1992, Thomas Blischok, manager of a retail
consulting group at Teradata, and his staff prepared an analysis of 1.2
million market baskets from about 25 Osco Drug stores. Database queries
were developed to identify affinities. The analysis did discover that
between 5:00 and 7:00 p.m. that consumers bought beer and diapers . Osco
managers did NOT exploit the beer and diapers relationship by moving the
products closer together on the shelves. This decision support study was
conducted using query tools to find an association. The true story is
very bland compared to the legend.
