With the ubiquity of Internet access, mobile devices, and wearables, there has been the unleashing of a torrent of data. Every second, Google processes over 40,000 searches or 3.5 billion a day. On a minute-by-minute basis, Snapchat users share 527,760 photos, and YouTube users watch more than 4.1 million videos. Then there are the old-fashioned systems, like emails, that continue to see significant growth. Every minute, there are 156 million messages sent.4
But there is something else to consider: Companies and machines also generate huge sums of data. According to research from Statista, the number of sensors will reach 12.86 billion by 2020.5
In light of all this, it seems like a good bet that the volumes of data will continue to increase at a rapid clip. In a report from International Data Corporation (IDC) called “Data Age 2025,” the amount of data created is expected to hit a staggering 163 zettabytes by 2025.6 This is about ten times the amount in 2017.
To deal with all this, there has emerged a category of technology called Big Data. This is how Oracle explains the importance of this trend:
Today, big data has become capital. Think of some of the world’s biggest tech companies. A large part of the value they offer comes from their data, which they’re constantly analyzing to produce more efficiency and develop new products.7
So yes, Big Data will remain a critical part of many AI projects.
Then what exactly is Big Data? What’s a good definition? Actually, there isn’t one, even though there are many companies that focus on this market! But Big Data does have the following characteristics, which are called the three Vs (Gartner analyst Doug Laney came up with this structure back in 20018): volume, variety, and velocity.
