The first half sets the join across three relational tables against an ontology of classes and predicates, the subject-predicate-object triple written as a turtle file, and a SPARQL query over it, and argues that the chain of relationships is what makes a recommendation traceable back to its reasons. The demo, taken from a Discovery Center mission, curates the ontology and the RDF files for an accounts receivable scenario in VS Code, ingests the triples into HANA Cloud with SQL and walks the resulting graph outward from a customer; that is the [graph, spatial and document data](capability:multi-model-data) edge. It closes by separating three things that share the name: the HANA Cloud knowledge graph engine, SAP Knowledge Graph as the data, and the knowledge graph in [SAP Business Data Cloud](artifact:btp-business-data-cloud).","short":"Building a knowledge graph on SAP HANA Cloud","explains":[{"ref":"artifact:btp-hana-cloud"},{"ref":"capability:multi-model-data","applies_to":{"ecosystems":["btp"]}}],"sources":[{"url":"https://www.youtube.com/watch?v=EVWfXGdSx9c","title":"Building your knowledge graph on SAP HANA Cloud","checked":"2026-10-19","quote":"today's session uh we are going to talk about building your knowledge graph on HANA cloud"},{"url":"https://www.youtube.com/watch?v=EVWfXGdSx9c","title":"Building your knowledge graph on SAP HANA Cloud","checked":"2026-10-19","quote":"So to keep it super simple ontology data knowledge graph three layers right?
