This course introduces the concepts of database technology used in Business Intelligence. More precisely, this includes multidimensional databases and data warehouses, as well as ETL processes. Necessary techniques will be presented for designing, implementing, exploiting, and maintaining data warehouses.
A particular focus will be given on the problems posed by heterogeneous data integration and data quality. The students will learn how to define, measure and maintain data quality in the context of data warehousing. Classical notions of data warehousing and OLAP are developed: ETL, architecture, conceptual and logical design, query processing and optimization. At the end of this course, the student will know how to efficiently design, construct and query a data warehouse.

Technical Competences of each Specialization
CEE5.1 - Capability to participate in improvement projects or to create service systems, providing in particular: a) innovation and research proposals based on new uses and developments of information technologies, b) application of the most appropriate software engineering and databases principles when developing information systems, c) definition, installation and management of infrastructure / platform necessary for the efficient running of service systems.
CEE5.3 - Capability to work in interdisciplinary engineering services teams and, provided the necessary domain experience, capability to work autonomously in specific service systems.
CEC2 - Capacity for mathematical modelling, calculation and experimental design in engineering technology centres and business, particularly in research and innovation in all areas of Computer Science.
Generic Technical Competences
CG3 - Capacity for mathematical modeling, calculation and experimental designing in technology and companies engineering centers, particularly in research and innovation in all areas of Computer Science.
CTR3 - Capacity of being able to work as a team member, either as a regular member or performing directive activities, in order to help the development of projects in a pragmatic manner and with sense of responsibility; capability to take into account the available resources.
CB7 - Ability to integrate knowledges and handle the complexity of making judgments based on information which, being incomplete or limited, includes considerations on social and ethical responsibilities linked to the application of their knowledge and judgments.
CB9 - Possession of the learning skills that enable the students to continue studying in a way that will be mainly self-directed or autonomous.

In these activities, the lecturer will introduce the main theoretical concepts of the subject. Besides lecturing, cooperative learning techniques will be used. These demand the active participation of the students, and consequently will be evaluated.
The course comprises theory, lab sessions and seminars.
Theory: The theory lectures comprise the teacher's explanations and constitute the main part of the course. The students will also have some contents to be read and prepared outside the classroom and will be asked to participate in cooperative learning activities.
Laboratory: Mainly, the lab sessions will be dedicated to the practice (with and without computer) of the concepts introduced in the theory lectures, by means of markable exercises that will be done during the class time. Some tools will be used for the design and practice on a specific DBMS (e.g., Oracle).
Final Mark = 60% min (10.1.1 * sum (Ci * Wi) / sum (Wi)) + 10% P + 30% E
Ci = Marks on collaborative activities and laboratories
Wi = Weight equal to 1, 2, 4, 6 or 8 (depending on the relevance and difficulty of the corresponding activity / laboratory)
P = Peer evaluation
E = Exam
Calculation of P: Students will have multiple mates in the activities carried out during the semester and those will report on them. Based on these reports, the teacher will assign a mark to each student.
