Objectives: Introduce advanced data management technologies that go beyond traditional (relational) database management systems and train students to evaluate the advantages and disadvantages of such technologies in different application contexts.

Prerequisites: Students should be familiar with basic concepts in databases (including relational databases, SQL, and relational algebra) and algorithms, as well as having good pogramming skills.


References: There is no single textbook that covers the entire course. The course material is collected from various textbooks and research papers. They are indicated on the slides.

More details are in the course presentation form.

The exercise part of the course consists in the elaboration of a project, which shall be done in groups of 2 students. The project consists in the development and implementation of a Data Warehouse.

The project is documented by a project report and concluded by a final presentation and demo.

Sample project reports: sample project 1, sample project 2.



The assessment of the course consists of two parts:

Both parts must be positive to pass the exam. The final grade is the weighted average between the two parts. A positive project is a pre-requisite to do the exam.

Here are some of the old exams: 02.02.2016, 15.09.2015, 06.07.2015, 28.01.2015, 10.06.2014, 10.02.2014.
