Whether it emerges from the company’s information system, social media, or connected objects, data is the precious resource of the digital economy. The proliferation of this data and how it is used, commonly known as “big data”, offer unparalleled potential to be sources of value for businesses and their clients. New types of jobs have emerged, such as data scientists and chief data officers. These are experts tasked with implementing the necessary architectures and infrastructure, collecting data, processing it and turning it into usable information through new indexing techniques. Big data has become even more important when combined with artificial intelligence. Machine learning and deep learning algorithms are particularly capable of optimising their processing as they go along, offering new options for data mining and decision-making. Beyond that, AI is becoming more and more a part of our everyday lives, upending numerous fields such as transportation, medicine, telecommunications, industry, trade, and more.
