When the size of structured and unstructured data exceeds the capacity of conventional database management systems, advanced tools and methods are required for capturing, storing and managing data. Such huge amounts of data are usually stored in large-scale distributed environments, processed using specific advanced data processing environments, and specific tools for their management are usually required. Semantic information plays a relevant role in this context and ethical issues need to be taken into account.
Learning the theoretical, methodological, and technological fundamentals of data management for advanced data processing architectures, with a specific reference to large-scale distributed environments, like key elements of NoSQL and stream-based systems as well as basic issues in parallel and distributed query processing, multi-query processing, and high-throughput transactional systems.
DESCRIBE the principles for data management in distributed systems, environments for large-scale data processing, systems for large-scale data management and approaches for data stream management
UNDERSTAND the differences between traditional data processing and management and large-scale (semantic) data processing and management
UNDERSTAND the differences between the presented approaches for large-scale (semantic) data management
UNDERSTAND the ethical implications of large-scale (semantic) data management

Written examination, oral examination (including project discussion).
Details on how to prepare for the examination and the required degree of knowledge for each topic will be provided during the lessons.
During the semester, we will propose some groupworks as well as a project, to be developed on one of the presented systems. The project is mandatory.
The written exam consists of a set of questions and exercizes on basic topics of the course; the goal of this test is to verify the understanding of the main issues addressed during the lessons.
The oral exam consists of an in-depth discussion of the solutions developed by the student for the given project, in order to assess whether the student has reached an appropriate level of knowledge.
For students that do not successfully complete the assignments, the oral exam will also include theoretical questions and / or practices of the course topics.
