The ever-changing face of the retail industry has impacted businesses all over the globe. Until recently, growing retailers struggled to keep track of their sales and expend inventory volumes. As they embraced an integrated IT architecture connecting stores to warehouses, home offices and vendors, the main challenge, ironically, was not a lack of data but an explosion of it. Retailers found it difficult to handle the burgeoning volumes of data and more importantly, extracting relevant insights. With the advent of analytics, backed by robust data management techniques, it is now possible to harness big data to make better plans and decisions for the future.
