Paolo Atzeni (University of Roma Tre) talked about model independent schema and data translation. The goal of the database research community is to develop the “information utility”: make it easy for everyone to store, organize, access and analyze the majority of human information online. Data is not just in databases, it is in mail messages, social networks, web pages, spreadsheets, textual documents, palmtop devices, mobiles, multimedia annotations, XML documents etc. Heterogeneity at the system level, model level, structural and semantic level means that it is challenging to achieve the information utility. Paolo talked about the challenges of schema and data translation, schema and data integration and data exchange between databases.
