The big data is a very comprehensive terminology and this blog post will explain the main three concepts which are volume, velocity and variety.
As Forbes (2012) states:
1. Volume indicates the essential characteristic of the big data trend, which is a massive amount of data (Gewirtz, 2018). To have a clearer idea of how massive is volume - we can think of 2 billion users on Facebook, 1 billion on YouTube and 700 million users on Instagram who contribute to billions of images, posts, and videos (Whishworks 2017). Many companies are in possession of a huge amount of data but are struggling to find ways to process it.
2. Velocity indicates the speed at which new data arrives; thanks to social networks and web portals, half-an-hour news is already slightly outdated, and content needs to be continuously updated. Another challenge, besides the speed at which data arrives, is the speed at which decisions are made after the ingress of the data. Some of this data needs to be processed right away and can’t tolerate the time it takes to store it. Industry calls this the “streaming data”. Some of the technologies used to handle this data are IBM’s InfoSphere Streams, Yahoo’s product S4 and Twitter’s product Storm (Dumbill, 2012).
3. By increasing the velocity and volume of big data, variety experiencing significant growth and that means a huge amount of heterogeneous data (Jain, 2016). The power of data is in its variety but processing data from the raw state to the state where data is ready to be consumed by the application often causes some loss. Processing tries to structure all the data but according to Muse (2017), only 20 % of data is structured and everything else has remained semi-structured or unstructured at all.
The real information is worth a fortune, but getting through the data forest has become increasingly difficult as never before. They are larger today than they were yesterday, and tomorrow they will be bigger than they are today.
