In the recitation lectures (2T) the main subjects are exposed and laboratory classes (2P). These are intended to be autonomously explored by students. There are written lecture notes and hand out slides, which closely follow the presentation in recitation lectures.
In the laboratory classes students explore tools that allow experimenting their use, as well as use the query languages for solving predefined problems and tasks.
Evaluation consists in 2 individual midterms (each worth 25% of the final grade), a final team project (35%), oral presentation and discussion of a colleague’s project (15% of the grade).
Each midterm has a minimum grade of 8/20 and the average of the midterms must be at least 10/20, after rounding.
Evaluation consists in 2 individual midterms (each worth 25% of the final grade), a final team project (50%), with an individul grade after an oral presentation and discussion. The average of the midterms must be at least 10/20, after rounding. Any student may me called to an oral discussion to replace de tests / exam component.
The tests and exam will be in person, with the possibility of consulting only one help sheet provided by the teachers.
1. NoSQL data models
Alternative models for storing big volumes of data. Column, document and graph models. Relational, semi-structured and graph data. Data modelling with graphs. Querying graph models. Graph databases. Relationship to NoSQL movement and key-value stores.
2. Semantic Web
Motivation. Linked Open Data. Language and semantics of the Resource Description Framework (RDF) and SPARQL query language. Ontologies in the Semantic Web: RDF Schema and Web Ontology Language (OWL).
3. Online Analytical Processing (OLAP)
Data Warehouses. (Conceptual) multidimensional data models. Typical OLAP operations and OLAP query languages. Metadata. Spatial and temporal dimensions. Interaction in the data analysis process.
4. Exercises and final project
Use of tools (graph database, temporal databases, RDF and OWL API, OLAP and multidimensional)
