A New Era for Graph Queries: ISO/IEC 39075 GQL

Session Track: Applications

Session Time:

Session description

The recently published new standard ISO/IEC 39075 GQL defines a unified graph database language inspired by Cypher and built upon the foundation of SQL. GQL boasts new features like a central object catalog, advanced pattern matching, richer type systems, and standardized error handling. This session explores GQL's capabilities and reveals how Neo4j Cypher is adapting to embrace this new standard.
