• 39 hrs lectures
• 13 hrs projects

• 51 pts final exam (written part)
• 15 pts mid-term test (written part)
• 34 pts projects

• Student is able to develop conceptual models of an application domain for database applications.
• He/she can develop database applications for relational databases, knows the standard database language for relational databases SQL, and has experience with some integrated development environment for database applications.  and have knowledge of relational database management system fundamentals.
• He/she receives basic competencies for database administrator's work like user account creation, access rights assignment and performance tuning.
• Student acquaints with fundamentals of some important functions of advanced database system like transactional processing, concurrency and recovery.
• Student acquaints with basic English terminology in the subject.

The student will learn how to analyze a given problem in a small team and he/she will learn to design and implement a solution of the problem individually. He/she learns to present and defend  both partial and final results of the project.

Mastering fundamentals of relational database theory and skill in using database technology at a level required for database design, development of database applications and database administration.

Since the 1960s, when data intensive applications and systems have been developed and used, typically information systems and their parts, database systems have been used to store data. Database technologies have evolved rapidly and are widely used today. It is, therefore, necessary for students to acquire competencies and skills in this field. This subject is focused on the basics of database technologies, namely relational databases that play a key role here.

Exam prerequisites:
To be allowed to sit for written examination student is present and defend project outcomes, and to earn at least 24 points during the semester.

Mid-term exam passing, realization and presentation/defence of projects in due dates. In the case of a reported barrier of the mid-term exam and to present/defend a project, a student will be offered a substitute date of the exam or an oral exam, and she/he will be allowed to present/defend the project in a substitute date, respectively.

To be allowed to sit for written examination student is present and defend project outcomes, and to earn at least 24 points during the semester.
