Big data brings rewards as online shopping firms get creative

Unlike visiting brick-and-mortar stores, online shopping may seem a lonely experience as there are no salespeople fawning on you or recommending things that they think would interest you.

Though they lack in human interaction, online websites do know what you are looking for, thanks to big data technology.

Big data usually includes data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and process data within a tolerable time.
