Knowledge Graphs on Datasphere and HANA Cloud. The...

The ability to enhance RAG with Vector search, Graph knowledge bases, or SQL Queries is fundamental. SAP recently announced the Datasphere capability to create Graphs, and there are some key differences between the graph capabilities in SAP HANA Cloud, the new announcement SAP Datasphere knowledge graph and the Intergation Suite capability called Graph:

1. SAP HANA Cloud has had a powerful graph engine for analyzing complex relationships in business data for a while now. It allows creating graph workspaces from existing tables/views, querying graphs using openCypher, writing custom graph algorithms, and visualizing graphs.

2. Datasphere Creating knowledge graphs manually is very costly, so SAP Datasphere comes to help by automatically pre-populating them using content already available in SAP Datasphere like connections to source systems, tables, foreign keys etc. SAP Datasphere knowledge graph is a new capability announced in March 2024. As data is onboarded and integrated into SAP Datasphere, it automatically creates an ontology representing the relationships in the data, including business context from SAP sources like S/4HANA

3. SAP Graph as an Integration Suite capability

Parallel to building Graphs from Databases, SAP Graph is an alternative unified API available on the SAP Business Technology Platform that provides access to a connected graph of SAP-managed business data, regardless of where the data resides.

SAP Graph is intended for building extension applications, such as workflow applications using low-code tools or event-driven applications, and it supports modern open standards like OData v4 and GraphQL

Conclusion

While the SAP HANA Cloud graph is more for custom graph algorithm development and analysis, the SAP Datasphere knowledge graph is an automated capability that provides a rich context for generative AI use cases by capturing complex data relationships and metadata. The two serve different but complementary purposes in the SAP data and analytics portfolio.
