Datas generated in particular by connected objects is of major economic interest and facilitates, for example, the targeted marketing. Netherless, their analysis requires specific "data science" techniques, as they are generally considered unstructured. According to the experts, data generated by objects (often of a personal nature) will become increasingly important in years to come in terms of service offerings and future business models.
