Educational goals

The course fills a gap in the knowledge and skills of the typical new IT Engineer graduate in relation to the needs of the respective labor market. More specifically, the topic of the course focuses on the management of a modern DBMS environment and the services that it supports. Includes theoretical and practical training in technologies and practices that represent general knowledge and skills, independent of the DBMS software (commercial or free) used. Upon successful completion of the course, students are able to:

  • Identifies, describes and explains the role and responsibilities of the DBMS Administrator in relation to the management of the system and the services it supports, as well as in the development of application development and management policies by the developers
  • Implements in practice all the sub-processes of installation, parameterization and configuration of a DBMS, specifying and implementing the sub-instances of the environment
  • Distinguishes and interprets the components of DBMS architecture and technology related to the management of the system cache and the records of the file with the history of the execution of the transactions (transaction log file)
  • Understands the ARIES algorithm and explains the sub-process of restoring the DBMS to full operation after a failure
  • It contrasts the various backup management strategies to restore the system content information to a specific past time point (recovery to point-in-time).
  • Integrates management strategies for individual DBMS functions, incorporating them into the automation provided by the latest
  • Evaluates system performance under specific operating conditions and calculates the impact of different data indexing strategies
General Skills
  • Assist the decision-making process of managing critical business data
  • Adaptation of collaborative application development processes to the capabilities provided by the modern relational data management system (DBMS)
  • Acquisition of know-how in improving the performance and operational reliability of DBMS through its indexing, and / or data sharing/distribution
  • Autonomous work
  • Teamwork
