Graph Generating Dependencies (GGDs) is a new class of dependencies for property graphs. Extending the expressivity of state of the art constraint languages, GGDs can express both tuple- and equality-generating dependencies on property graphs, both of which find broad application in graph data management. The paper provides the formal definition of GGDs, analyzes the validation problem for GGDs, and demonstrates the practical utility of GGDs.Back
