The analytics core: SAP Business Data Cloud
SAP describes Business Data Cloud (BDC) as the trusted data foundation for the SAP Business AI Platform: a business data fabric that connects data, semantics, processes, and policies while preserving the business context that gives data meaning. Irfan Khan, president and chief product officer of SAP Data & Analytics, set out the TechEd additions in an October 29 post. Four of them change how I would draw a target architecture; a fifth changes how you run the database underneath.
An open lakehouse, built on Dremio
SAP completed its acquisition of Dremio on July 6, 2026, and TechEd showed what it becomes inside BDC. According to SAP's guide, new lakehouse capabilities will provide native support for Apache Iceberg and a distributed SQL query engine: a native Iceberg catalog based on Apache Polaris, integrated with the BDC catalog, and an engine that can query a variety of lakehouse catalogs and relational databases. BDC already supports Delta Lake; Iceberg is the addition. Khan's post adds the working detail — federated queries across lakehouses and relational databases, including SQL Server, MongoDB, Oracle, and Postgres, without moving data, and Dremio's Reflections technology, which learns from how data is used and automatically precomputes and optimizes the results workloads need, adapting as those workloads change. Through Joule Work, business users will be able to question this data in natural language. SAP plans general availability of the lakehouse capabilities for Q1 2027.
Dating note: SAP's own sources differ in tense here. Khan's October 29 post says BDC "now supports" native Apache Iceberg and a Polaris-powered universal catalog; SAP's innovation news guide, published two days earlier, plans general availability of the lakehouse capabilities for Q1 2027. I plan against the guide's date. Until the capability shows up as generally available for your landscape, treat Iceberg in BDC as roadmap, not as a dependency.
Business context you can curate: BDC Ontology Manager and SAP Knowledge Graph
The second theme is context — the thing SAP keeps saying agents lack. SAP Knowledge Graph already provides business context about a customer's SAP systems; the new SAP Business Data Cloud Ontology Manager adds an AI-assisted way to curate domain-specific ontologies on top of it: focused, reusable business context for particular applications and agents. Developers select the context relevant to a custom agent and publish a domain view for a specific business problem — SAP's examples include understanding customers, investigating equipment failures, and recommending next best actions. Khan's example makes it concrete: a collections agent needs customers, invoices, payment terms, and credit risk, so a team publishes a collections view, and because views inherit definitions and governance from the Knowledge Graph, the same semantics can be reused for cash flow or order management without being redefined. Ontology Manager will work with both SAP data products and customer-managed data products, and SAP says reuse helps reduce time and token use. Its beta is planned for November 2026.
The Knowledge Graph itself is widening. It has traditionally drawn on data from specific SAP applications; new capabilities will add information in SAP-managed data products, customer-managed data products in BDC, and data in extensions of SAP Autonomous Suite offerings, so Joule can ground its answers in each customer's own landscape. SAP's press release adds that users will be able to query and explore this customized data in natural language. General availability for all features is planned for Q1 2027.
Master data as data products: SAP Reltio
SAP Reltio — multi-domain master data management based on technology from Reltio, which SAP acquired earlier this year — has been generally available in BDC since SAP Connect in October. Its AI-based entity resolution matches and reconciles records across SAP and third-party systems into unified views of customers, suppliers, products, and other entities, and those trusted profiles can be published as governed data products in BDC for Joule and Joule Agents to use. At TechEd, SAP added support for building unified data products; together with SAP Master Data Governance in BDC, SAP says this will deepen native master data management inside the fabric. General availability of the SAP Reltio data-product capabilities is planned for Q1 2027.
SAP Databricks gets more of the Databricks platform
SAP also expanded its Databricks partnership, bringing Lakeflow, Agent Bricks, Unity Gateway, and Lakebase to SAP Databricks inside BDC. Alongside it, a new SAP Application Data Foundation makes data from SAP applications available for consumption in the BDC engine of your choice, including SAP Databricks, and the resulting SAP data products can then be shared zero-copy through SAP BDC Connect. SAP also announced an integration between Joule and Databricks' Genie. Neither the press release nor Khan's post gave availability dates for these items, so I treat them as announced, with timing to be confirmed.
Joule for SAP HANA Cloud administration
Finally, new Joule agentic capabilities in SAP HANA Cloud will give database administrators a conversational interface to monitor system health, troubleshoot issues, optimize database and SQL performance, and manage lifecycle operations, with AI-assisted diagnosis and remediation. SAP's rationale is one every platform team will recognize: AI and agent workloads raise query volumes and make resource consumption harder to predict. General availability is planned for Q4 2026.
My read: The lakehouse is the most consequential announcement of the event for data architects, because it changes what BDC is. Until now the pitch was a governed SAP fabric that reaches other platforms through zero-copy connectors; with native Iceberg, a Polaris-based catalog, and a federated SQL engine, BDC also becomes a place where open tables are stored, cataloged, and queried in place. That is good news for estates that standardized on open table formats — and it raises questions to get answered before Q1 2027: which catalog is authoritative for which tables, how BDC governance applies to federated sources, and how automatic precomputation shows up in your capacity consumption. On context, Ontology Manager is the right design instinct: it is the semantic-layer pattern we already use — subject-area views on a shared, governed model — applied to agents. Treat the November beta as a place to learn, not something to build production dependencies on.
