What is Big Data?




It cannot have escaped your notice that researching, interacting and purchasing on mobile devices, particularly tablets and mobile phones has greatly increased in recent years. The Guardian reported that in 2014, for the first time, shopping from mobile devices had overtaken that from the desktop. Social media is of course, everywhere. Combine this structured and unstructured data from a company's website, mobile site, social media, loyalty cards, phone systems, catalogue purchases and brick based sales and you have a mass of data.

So what is Big Data? There are numerous definitions in use but most use the terms colloquially called "the 3 Vs" - Volume, Variety, and Velocity. When you have a large volume of multitudes of different types of data, arriving, moving and leaving at a high velocity you have Big Data.

When we say Big Data we mean BIG! Until very recently this data was so large and so unstructured that current technology could not measure it. NASA in 1997, first coined the term, indicating that it was then impossible to be stored on a hard drive. In 2011, McKinsey defined Big Data as: "datasets whose size is beyond the ability of typical database software tools to capture, store, manage, and analyze," Imagine then, how difficult it has been to analyse this volume of data? That is until Omnichannel software arrived.
