I sistemi di database sono diventati fondamentali nei sistemi di gestione delle informazioni, contribuendo allo sviluppo di una società sempre più basata sulla conoscenza. Tutte le moderne applicazioni IT sfruttano un database per la memorizzazione, l’elaborazione e il recupero delle informazioni. Viene quindi presentato il linguaggio SQL per l’interazione con un database relazionale e vengono introdotti i problemi di progettazione dei sistemi che interagiscono con i database. Infine, le tecnologie dei moderni sistemi di database sono descritte utilizzando il DBMS Oracle. Database Systems have become fundamental in information management systems, contributing to the development of an increasingly knowledge-based society. All modern IT applications now exploit a database for storing, processing and retrieving information. The course illustrates the basic concepts for understanding not only database models and their evolution, but also the principles of their conceptual, logical and physical design within so-called information systems. The SQL language for interaction with a relational database is then presented and the problems of designing systems that interact with databases are introduced. Finally, the technologies of modern database systems are described by using the Oracle DBMS.
An excellent online course offered by edX: how it works
edX courses consist of weekly learning sequences. Each learning sequence is composed of short videos interspersed with interactive learning exercises, where students can immediately practise the concepts from the videos. The courses often include tutorial videos that are similar to small on-campus discussion groups, an online textbook, and an online discussion forum where students can post and review questions and comments to each other and teaching assistants. Where applicable, online laboratories are incorporated into the course.
edX offers certificates of successful completion and some courses are credit-eligible. Whether or not a college or university offers credit for an online course is within the sole discretion of the school. edX offers a variety of ways to take courses, including verified courses where students have the option to audit the course (no cost) or to work toward an edX Verified Certificate (fees vary by course). edX also offers XSeries Certificates for completion of a bundled set of two to seven verified courses in a single subject (cost varies depending on the courses).
