The 3 Vs of Big Data


On the last post, we talked about what is Big Data with an overview of it where we had a preview about the 3 Vs of Big Data as well. Now we are going to talk about it with more details, exploring examples that make easy to understand. 
Big data is data that contains a greater variety arriving in increasing volumes and with ever-higher velocity. This is known as the three Vs (Oracle, 2020). 





Volume 
This refers to the amount of information generated by websites, platforms, social media, apps, systems and so on, for billions of users every moment, every day. It means that every single interaction by the user generates a piece of information if we just look at social media, for instance, Facebook has around 2 billions of users (Whishworks, 2017) and every like, every post and comment made by them creates data which can be lately analysed or even in real time. It is already a huge amount of information, now imagine all the Data is generated for all of these online networks together. 
The amounts of data rang by kilobytes (text document) to a few gigabytes (movie file) and can also be generated for machines as for example weather sensors, GPSs, smartphones and so on. 

Velocity 
Velocity is the fast rate at which data is received and (perhaps) acted on (Oracle, 2020) The speed of data can be analysed by using a batch process, bits or stream. With the spread of mobile phones and internet Data has been processed in real-time with a stream for example. Every day 900 million pictures are uploaded on Facebook (Whishworks, 2017). Looking to all the available online platforms this massive amount of data being streamed on real-time keeps demanding new technologies that follow this exponential growth. 

Variety 
That regards to the different types of data created, can it be structured as texts messages, twitters, photos and videos and so on, and semistructured as voice messages, audio recordings, handwriting and emails. It either can be produced by humans or machines. Variety is about the ability to classify the incoming data into various categories (Whishworks, 2017).

AI marketing is strongly connected with machine learning and uses it to create personalized offers to customers focusing on improving their experience. But before we get started on it, let’s see the definition of AI and Machine learning. AI can be understood as the simulation of human intelligence applied to machines that are programmed to think like humans and mimic also (Investopedia, 2020). On this context Machine Learning is a part of AI that makes possible a system to learn from data instead of programming (IBM,2020). How marketing can be benefited by Machine Learning? The key factor is the data analysis made by this technology. By  analysing  historical data from different sources of a business Machine Learning can improve communication, targeting and offers that contribute create successful campaigns (Smart Insights, 2020). Furthermore, the algorithms for Machine Learning create perceptions from predictive analytics that marketers can use to define act...

Value in Big Data for Marketing

Big Data has a huge amount of aspects that can be measured in terms of value, but before measuring that it is important to define what part of it is more relevant for an expected business outcome, it means that the value of Big Data will appear depending on the business perspective or objectives.  According to (Rossi, 2015) It is how we make use of data that allows us to fully  recognize  its true value and potential to improve our decision-making capabilities and, from a business standpoint, measure it against the result of positive business outcomes.   The most common ways to verify the value of Big Data are through the three Vs of it, see the post-https://newdatadbs.blogspot.com/2020/02/the-3-vs-of-big-data.html .  However,   there are other perspectives that can be taken into account as highlighted by (Big Data Framework, 2018):   Transparency - It can be used to determine future decisions, that makes a company more tra...
