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 (Extraction, Transformation and Load) processes and basic concepts of dashboarding. Necessary techniques will be presented for designing, implementing, exploiting, and maintaining data warehouses, paying special attention to spatio-temporal data.
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 to create effective visualizations.

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. Objectives:123 Contents:
Theory: Inverted class techniques will be used, which require that the student work on the provided multimedia materials before the class. Then, theory lectures comprise the teacher's complementary explanations and problem solving.
Laboratory: Some representative tools will be used for the application of theoretical concepts (e.g., Indyco Builder, PotgreSQL, Oracle, Pentaho Data Integration, Tableau). The course includes continuous hands-on through a course project, divided into three logical blocks: data warehouse modelling, data integration and migration (ETL), and descriptive visualisation, in which the students will work in teams. There will be three project deliverables outside the class hours, while in the class the students will be as well individually assessed about the knowledge acquired during each project block.
Specifically, it will be assumed knowledge on:
- UML class diagrams
- Relational algebra
- SQL queries
- Relational views
- B-tree operations (i.e., insertion and splits)
- Basic concepts on physical query optimization
