As graph databases become widespread, the International Organization for Standardization (ISO) and Electrotechnical Commission (IEC) have approved a project to create GQL, standard property query language. This complements SQL/PGQ project, which specifies how define views over SQL tabular schema, run read-only queries against them.
We report on a community effort between industry and academia to shape the future of property graph constraints. The standardization for query language is currently underway through ISO Graph Query Language (GQL) project. Our position that this project should pay close attention schemas constraints, focus next key main purposes keys are enforcing data integrity allowing referencing identifying objects. Motivated by use cases from our partners, we argue constraints be able have different...
SQL:2016 (officially called ISO/IEC 9075:2016, Information technology - Database languages SQL) was published in December of 2016, replacing SQL:2011 as the most recent revision SQL standard. This paper gives an overview important new features SQL:2016.
Given the growing popularity of graphs, data models like Property Graph and corresponding query languages Cypher, have become popular in industry research. However, real-time graph analysis management are increasingly important for today's businesses. Still, lack features to handle streaming their continuous evaluation. % This demonstration showcases Seraph, a Cypher-based language supporting native querying features. Seraph is formally defined, declarative, backwards compatible with Cypher....
The scientific community has been studying graph data models for decades. Their high expressiveness and elasticity led the to design a variety of query languages, practitioners use them model real-world cases extract useful information. Recently, property graphs and, in particular, Cypher 9 (the first open version well-known Neo4j Inc.'s language) are gaining popularity. Practitioners find applicable many scenarios. However, we living streaming world where continuously flows. A growing...
Graph data management is instrumental for several use cases such as recommendation, root cause analysis, financial fraud detection, and enterprise knowledge representation. Efficiently supporting these yields a number of unique requirements, including the need concise query language graph-aware optimization techniques. The goal Linked Data Benchmark Council (LDBC) to design set standard benchmarks that capture representative categories graph problems, making performance systems comparable...
As graph databases become widespread, JTC1 -- the committee in joint charge of information technology standards for International Organization Standardization (ISO), and Electrotechnical Commission (IEC) has approved a project to create GQL, standard property query language. This complements extend SQL with new part, SQL/PGQ, which specifies how define views over an tabular schema, run read-only queries against them. Both projects have been assigned ISO/IEC SC32 working group Database...
