Data Management (academic year 2023/2024)

For whom is this course. This 6 credits course is for the students of the Master of Science in Engineering of Computer Science (School of Engineering) of the Sapienza Università di Roma. This course is also for students of the Corso di Laurea Magistrale in Ingegneria Gestionale of the same School. The language for both the course and the exam is English. The lectures are held in the second semester (February 2024 - May 2024).
Prerequisites. A good knowledge of the fundamentals of Programming Structures (algorithms and data structures), Programming Languages, Databases (SQL, relational data model, Entity-Relationship data model, conceptual and logical database design), Theoretical Computer Science (computational complexity, computability) is required.
Course goals. The course presents the basic concepts of data management systems. Several major issues related to the theory and the design of data management systems are covered, including NoSQL databases, transaction management, concurrency control, recovery, file and index organizations, query processing.
