Big data is a popular term for describing the exponential growth, availability and use of information, both structured and unstructured. Much has been written on the big data trend and its potentiality for innovation and growth of enterprises. The advise of IDC (one of the premier advisory firms specialized in information technology) for organizations and IT leaders is to focus on the ever-increasing volume, variety and velocity of information that forms big data. In most cases, such huge volume of data comes from multiple sources and across heterogeneous systems, thus, data have to be to linked, matched, cleansed and transformed. Moreover, it is necessary to determine how disparate data relates to common definitions and how to systematically integrate structured and unstructured data assets to produce useful, high-quality and up-to-date information. The research area of Data Integration, active since 90s, provided good techniques for facing the above issues in a unifying framework, Relational Databases (RDB), with reference to a less complex scenario (smaller volume, variety and velocity). Moreover, simpler forms of integration among different databases can be efficiently resolved by Data Federation technologies used for DBMS today. Adopting RDB as a general framework for big data integration and solving the issues above, namely volume, variety, variability and velocity, by using more powerful RDBMs technologies enhanced with data integration techniques is a possible choice. On the other hand, new emerging technologies came into play: NOSQL systems and technologies, datawarehouse appliances platforms provided by the major software players, data governance platforms, etc. In this talk, prof. Sonia Bergamaschi will provide an overview of this exciting field that will become more and more important.

Short Bio

Sonia Bergamaschi was born in Modena (Italy) and received her Laurea degree in Mathematics from Universitài Modena on 1977. She is currently full professor of Computer Engineering at the Engineering Department .Enzo Ferrari. - Universitài Modena e Reggio Emilia and leads the "DBGROUP", i.e. the database research group ( Her research activity has been mainly devoted to knowledge representation and management in the context of very large databases facing both theoretical and implementation aspects. Recently, her research efforts has been devoted to Big Data and Big data Analytics. Sonia Bergamaschi was coordinator and participant of many ICT european projects. She has published more than one hundred international journal and conference papers and her researches have been funded by the Italian MURST, CNR, ASI institutions and by European Community projects. She has served on the committees of international and national Database and AI conferences. She is a member of the IEEE Computer Society and of the ACM.
