21.13 Reference Architectures & Architect Labs

Reference A — SAP-centric enterprise​

S/4HANA + BW/4HANA -> Datasphere -> SAC

Use semantic onboarding, governed modeling and controlled analytical consumption.

Reference B — Hybrid enterprise​

SAP + cloud warehouse + object storage + APIs -> Datasphere -> enterprise analytics

Use multiple integration patterns and keep ownership explicit.

Reference C — Domain data products​

Domain sources -> domain spaces -> governed data products -> shared consumption

Use when multiple business domains need reusable data capabilities.

Lab 1 — Architecture selection​

Given:

  • 50 SAP sources
  • 10 non-SAP sources
  • 5,000 users
  • near-real-time operational analytics
  • monthly executive reporting

Design integration, semantic, security and consumption layers.

Lab 2 — Cost pressure​

A platform has growing storage and integration workload. Propose changes without violating freshness SLOs.

Lab 3 — Security isolation​

Finance and HR share a common employee-related dimension but have different access requirements. Design the sharing and security model.

Lab 4 — Acquisition failure​

An S/4HANA source becomes unavailable for six hours. Define impact, fallback, recovery and reconciliation.

Lab 5 — Architecture review​

Review a proposed design containing one giant space, copied datasets for every consumer and dashboard-level metric definitions. Identify at least ten architectural weaknesses.
