Abstract
This lecture introduces graph data management through the property graph model and the new standard graph query languages GQL and SQL/PGQ. After briefly connecting property graphs to familiar conceptual and relational models, we focus on what is distinctive about modern graph querying: declarative graph pattern matching, treating paths as first-class citizens, and the principled, formal treatment of graph traversals. Throughout, we illustrate these ideas with real-world cases such as recommendation, fraud detection, and knowledge graph querying.
