150 Hours (= 6 ECTS)

• written assignments and oral reviews of these assigments.
• written assigment/exam (closed book) - according to current planning in presence. If the pandemic situation will not allow exams in presence at the scheduled time, we will switch to an on-line assessment via TUWEL. In case of low enrollment, this assigment can also be conducted orally (also depending on the development of the pademic situation.

Acceptance to the course will be by the lecturers. Priority is given to

1. Students that have this course as a compulsory course (e.g. foundations, core modules) in their curriculum.
2. Students that have this course as an elective course.
3. ERASMUS students that have "Business Intelligence" in their learning agreement.
4. Students that are currently in a bachelor programme of any of the studies mentioned in 1.), and are finishing their studies in the current semester.
5. If there are still free places afterwards, they will be assigned according to the ranking on the waiting list

Students should have a solid grasp on:

1. Conceptual database design
2. Relational database model
3. Normalization
4. DBMSs
