The research objective is to improve decision-making in different fields of application (education, medical field, etc.) through the development of decision-making information systems. The decision-making systems in question are essentially based on a data-driven approach (warehousing, data mining, online data analysis). Also, with the proliferation of data available to a company or establishment, the volume of data continues to grow. These data take different forms and formats and they are also produced at accelerated rates, as is the case with the data produced at all times by social networks as well as the data produced by connected objects (Internet of Things).

The data thus characterized is qualified as massive data (or BIG DATA). BIG DATA presents and offers new opportunities for its analysis and poses new challenges compared to traditional data stored in data warehouses.

Thus, we will pursue the objective of integrating big data into the decision-making process and developing decision-making systems adapted to this type of data.
