Bridging Courses
It is suggested (not mandatory) to take the Database exam after courses on computer programming, computer architectures, algorithms and data structures, operating systems.
Learning Achievements (Dublin Descriptors)
Knowledge and understanding: the student will acquire the main knowledge related to database design methodologies, SQL query language, architecture of database management systems; he will be able to understand the structure of information systems designed according to the relational model. In addition, the student will acquire the main knowledge related to the extraction of information from data analysis.
Ability to apply knowledge and understanding: the student will be able to apply the acquired knowledge to design relational databases and implement them using systems such as MySQL. It will also be able to develop a project for the construction of an IT system. Finally, he will be able to understand and (partially) apply data mining techniques for extracting information from a set of raw data.
Autonomy of judgment: the student will be able to evaluate the correctness and efficiency of a database designed according to the relational model.
