OVERVIEW

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.

AIMS AND CONTENT

LEARNING OUTCOMES

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.

AIMS AND LEARNING OUTCOMES

At the end of the course, students will be able to:

6 CFU 

DESCRIBE the principles for data management in distributed systems, environments for large-scale data processing, and systems for large-scale data management

UNDERSTAND the differences between traditional data processing and management and large-scale data processing and management

UNDERSTAND the differences between the presented approaches for large-scale data management 

SELECT the system and the methodology for large-scale data management, suitable in a given application context

USE some of the presented systems for large-scale data management, for solving simple problems

USE at least one of the presented systems for large-scale data management for solving non-trivial problems

ANSWER questions related to large-scale data management

SOLVE exercizes related to the data design in some of the presented systems and the interaction with such systems, through the available languages

EXAMS

EXAM DESCRIPTION

Written examination (a different number of questions will be proposed depending on the number of the CFU); project development (mandatory); oral examination

During the semester, we will propose some groupworks, to be developed on one of the presented systems. 

ASSESSMENT METHODS

Details on how to prepare for the examination and the required degree of knowledge for each topic will be provided during the lessons.

The written exam consists of a set of open and closed questions and exercises on basic topics of the course: the goal of open and closed questions is to verify the understanding of the main issues addressed during the lessons, the aim of exercises is to check the ability to select the right system for a given scenario and solve simple problems related to data modeling and querying in large-scale data management systems.

The project consists in the design and the implementation of a data store for one of the systems presented in the course; the presentation of the performed activity help us in checking the ability of using at least one system for large-scale data management for solving non trivial problems and the ability of communicating t(in a written way) he result of the activity in a clear and complete way. 

The oral exam consists of the presentation 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 and the ability of communicating (in an oral way) the result of the activity in a clear and complete way. 

For students that do not successfully complete the assignments, the oral exam will also include theoretical questions and / or practices of the course topics to better understand the understanding of the main issues addressed during the lessons.
