PG-Schema: Schemas for Property Graphs
Renzo Angles, Angela Bonifati, Stefania Dumbrava +18
Property graphs have reached a high level of maturity, witnessed by multiple robust graph database systems as well as the ongoing ISO standardization effort aiming at creating a ne…
Graph Pattern Matching in GQL and SQL/PGQ
Alin Deutsch, Nadime Francis, Alastair Green +15
As graph databases become widespread, JTC1 -- the committee in joint charge of information technology standards for the International Organization for Standardization (ISO), and In…
Semantic Foundations of Seraph Continuous Graph Query Language
Emanuele Falzone, Riccardo Tommasini, Emanuele Della Valle +6
The scientific community has been studying graph data models for decades. Their high expressiveness and elasticity led the scientific community to design a variety of graph data mo…
The Future is Big Graphs! A Community View on Graph Processing Systems
Sherif Sakr, Angela Bonifati, Hannes Voigt +38
Graphs are by nature unifying abstractions that can leverage interconnectedness to represent, explore, predict, and explain real- and digital-world phenomena. Although real users a…
Conjunctive Queries with Theta Joins Under Updates
Muhammad Idris, Martín Ugarte, Stijn Vansummeren +2
Modern application domains such as Composite Event Recognition (CER) and real-time Analytics require the ability to dynamically refresh query results under high update rates. Tradi…
Schema Validation and Evolution for Graph Databases
Angela Bonifati, Peter Furniss, Alastair Green +3
Despite the maturity of commercial graph databases, little consensus has been reached so far on the standardization of data definition languages (DDLs) for property graphs (PG). Th…
G-CORE: A Core for Future Graph Query Languages
Renzo Angles, Marcelo Arenas, Pablo Barceló +9
We report on a community effort between industry and academia to shape the future of graph query languages. We argue that existing graph database management systems should consider…
Living in Parallel Realities -- Co-Existing Schema Versions with a Bidirectional Database Evolution Language
Kai Herrmann, Hannes Voigt, Andreas Behrend +2
We introduce end-to-end support of co-existing schema versions within one database. While it is state of the art to run multiple versions of a continuously developed application co…
