Università Roma Tre
Big Data & Databases Research Group


The group is devoted to the development of new principles, methods and tools for the organization and management of information, in the form of databases. The focus is on the new requirements generated by the availability of big data, i.e., massive amounts of information whose size exceed the capacity of conventional database systems. The data in the sources can be heterogeneous, unstructured, and inconsistent and the goal is to work for effective and scalable solutions for their extraction, integration, management and analysis. The overall approach is to tackle problems that have a practical significance, providing both general methods (with a theoretical background if relevant) as well as concrete tools that demonstrate the approach.
