From Thousands of Tables to an Ontology Graph: Building an AI Agent with Doris and PuppyGraph
AI agents increasingly need to understand relationships across thousands of enterprise tables, but traditional Text-to-SQL approaches struggle with complex, multi-hop relationships. In this talk, we will show how a PuppyGraph-powered agent automatically discovers entities, relationships, and semantics across thousands of tables to generate an ontology graph. PuppyGraph then queries the existing Apache Doris data directly as a graph—without ETL, data migration, or creating a second copy of the data. We will demonstrate how this architecture enables AI agents to combine SQL analytics with graph traversal for complex questions across large-scale enterprise data.
