**The course will be held in the first half of the semester.**
The main topic of the course is the graph database engine Neo4j and its query
language CYPHER. During the labs we are going to query various interesting
graph data collections available (e.g., Paradise papers, Russian trolls).
Addtionaly, we can spend some time on RDF & SPARQL (see [Wikidata Query
Service](https://query.wikidata.org/)), Apache TinkerPop & Gremlin, Spark and
GraphX/GraphFrames.
