Reference Architectures

Pattern A — SAP-centric​

S/4HANA → Datasphere → Semantic Models → SAC

Use when the primary objective is governed SAP analytics with limited external integration.

Pattern B — Hybrid enterprise​

S/4HANA + BW/4HANA + Non-SAP → Datasphere → Domain Models → SAC/BI

Use when existing investments must coexist while the enterprise progressively modernizes.

Pattern C — BDC-oriented​

SAP applications → Business Data Cloud → Datasphere + data products → analytical/AI consumers

Use when the enterprise is adopting the broader SAP Business Data Cloud operating model.

Pattern D — Federated enterprise​

Cloud warehouses + databases + SAP sources → Datasphere semantic layer → governed consumers

Use when source ownership remains distributed and copying every dataset would be wasteful.

Pattern selection​

Choose the simplest architecture that satisfies:

business value + semantics + security + performance + resilience + operations + cost

More boxes do not make an architecture more enterprise-ready.
