Data science, advanced telecommunication infrastructure and technological developments in IT brought frameworks for handling tremendous `big’ data volumes at our disposal. Among others, social media and e-commerce applications feed these volumes with new (kinds of) data, new opportunities and new challenges. Four important kinds of problems that can manifest themselves in this new way of data usage have been identified and are related to Volume (Big data), Variety (Varied data), Velocity (Fast data) and Veracity (Bad data).
DDCM has expertise in NoSQL and NewSQL database technology and is actively researching solutions for veracity problems. This part of our research is closely connected to our research on data quality. We also investigate new (semi-automatic) ways to improve the semantic interpretation of data in schemaless NoSQL database systems.
