Students will acquire the knowledge about different aspects of database management systems implementation and their impact on development and management of complex information systems. The course prepares students for the qualified evaluation of modern database systems characteristics, their effective implementation, tuning and administration.
- apply the acquired knowledge about database system architecture
- apply the acquired knowledge about physical data organization in database systems
- apply the acquired knowledge about principles of query optimization
- apply the acquired knowledge about recovery in database systems
- apply the acquired knowledge about concurrency control
- apply the acquired knowledge about distributed database systems characteristics
Forms of Teaching
Theoretical fundations and paradigms exposed during the lectures are illustrated with practical examples.
