The textbook provides a systematic and comprehensive introduction to modern database systems. The currently dominant relational database technology is presented in great detail. The book emphasizes the practical aspects of the database field while not neglecting the theoretical foundations. A continuous example application illustrates the concepts, making the work also excellent for self-study. The expanded 10th edition updates the presentation of the most important new developments: in-memory database systems and big data applications. The rapid development in these areas necessitates this update. All major manufacturers have now developed in-memory databases that will soon replace traditional database technology. The growing importance of big data applications must also be taken into account.
