Abstract

This paper provides an introduction to the world of graph databases and explores the fundamental concepts that make the use of graphs for data storage appealing. It presents two graph models, RDF (Resource Description Framework) and Property Graph, and compares them not only based on their conceptual differences but also in terms of their query languages, focusing on Oracle’s implementation of the Property Graph Query Language (PGQL). Additionally, the paper serves as a tutorial for working with Oracle and Property Graphs, with a specific focus on creating PGQL queries for a graph representing football transfers in the German Bundesliga since the 1992/93 season. Furthermore, the paper offers insights into the future development of Property Graph query languages in the form of Graph Query Language (GQL).
