    • Database and Database management system

      • Purpose of the database module: 

        This course should enable the student to identify the importance of structuring and manipulating data in a tabular form. Through the relational model and its underlying relational algebra, which are more practice-oriented, the student should understand the significance of data structuring, the concept of data independence from processing, as well as data integrity and consistency.
