There are two types of data to analyze;

  • Structured data that can be easily sorted, read and organized automatically with a system. This group includes, for example, data collected from services, products, and electronic devices, such as website traffic data, sales figures, bank details, or GPS coordinates collected from a smartphone.
  • Unstructured Data. This is the fastest growing form of Big Data. This is data from people's input, such as customer reviews, emails, and social media posts. This data is harder to sort and classify in an automated way.

For companies, it is getting more and more important to take advantage of this last type of data to be able to define and reach new goals, able to increase competitiveness and turnover.
