Goal

Over the last few years, research on database and information system technologies has been rapidly evolving thanks to the new paradigms of software and hardware adopted by modern scientific and more invasive applications. Presently, huge and heterogeneous amount of data can be efficiently collected, integrated, stored, managed, and analyzed for novel and more interesting data-driven applications. The growing relevance of non-traditional domains such as bioinformatics, social networking, mobile computing, sensor applications,smart cities, and gaming are generating increasing quantities of data - complex in contents, heterogeneous in formats, and often order of Terabytes in amount. These novel domains result in articulate ecosystems that include areas such as human resources, business processes, IoT, mobile equipment, etc.

This scenario provides unprecedented opportunities to work on exciting problems, but also raises many new challenges for data management, storage, process and mining. Heterogeneous data collected from different sources should be adequately combined, integrated and stored to ensure efficient and effective data exploration and understanding. Moreover, while information sharing is essential in todays business and social networks, such sharing should not violate security and privacy requirements. Particular attention should also be devoted to the involvement of the end-user in the entire process to enhance her/his exploitation and understanding of data and knowledge as well as to make the user a valuable data provider. Data management and analytics solutions will perform better when users can interact with systems and the systems take account of the cognitive and physiological characteristics of the people involved to provide personalized data processing and analytics.

The aim of this special issue is to disseminate cutting-edge contributions from various application domains representing new trends in the far reaching research areas of databases, information systems and data analytics.
