Learning outcomes of the course unit
The course is divided in two parts. The goal of the first part is to introduce Data Base Management Systems, with special regard to those based on the relational data model, and the many ways to interact with them. The second part of the course introduces the methodologies and techniques that are needed for a correct design of a relational database.
During the course, the student will also be introduced to the use of a specific Data Base Management System.
The knowledge of basic programming languages concepts is mandatory. The knowledge of the basic concepts of operating systems and communication networks is also helpful (even though not strictly required).
