GraphAlg Playground: An Online Platform for Learning and Experimenting with the GraphAlg Language
Daan de Graaf, Robert Brijder, Soham Chakraborty +3
The GraphAlg language for graph algorithms enables native support for user-defined graph analytics workloads in databases. In this demonstration, we present a web-based playground…
Optimizing Navigational Graph Queries
Thomas Mulder, George Fletcher, Nikolay Yakovets
We study the optimization of navigational graph queries, i.e., queries which combine recursive and pattern-matching fragments. Current approaches to their evaluation are not effect…
Seeing the Trees for the Forest: Leveraging Tree-Shaped Substructures in Property Graphs
Daniel Aarao Reis Arturi, Christoph Köhnen, George Fletcher +2
Property graphs often contain tree-shaped substructures, yet they are not captured by existing proposals for graph schemas; likewise, query languages and query engines offer little…
Algorithm Support for Graph Databases, Done Right
Daan de Graaf, Robert Brijder, Soham Chakraborty +3
Graph database query languages cannot express algorithms like PageRank, forcing costly data wrangling, while existing solutions such as algorithm libraries, vertex-centric APIs, an…
Meta-Property Graphs: Extending Property Graphs with Metadata Awareness and Reification
Sepehr Sadoughi, Nikolay Yakovets, George Fletcher
The ISO standard Property Graph model has become increasingly popular for representing complex, interconnected data. However, it lacks native support for querying metadata and reif…
Identity Management for Agentic AI: The new frontier of authorization, authentication, and security for an AI agent world
Tobin South, Subramanya Nagabhushanaradhya, Ayesha Dissanayaka +18
The rapid rise of AI agents presents urgent challenges in authentication, authorization, and identity management. Current agent-centric protocols (like MCP) highlight the demand fo…
