des-silver-layer-design

A silver layer transforms bronze and source-derived data into cleaned, conformed, deduplicated, keyed, validated, and traceable entity/event datasets. It ensures downstream gold marts safely consume trusted, privacy-handled, and lineage-trackable data.

Design silver datasets by specifying scope, bronze-to-silver mappings, grain, identity, key strategy, deduplication, and data quality rules. You also define standardization, normalization, privacy handling, and lineage requirements to produce a complete silver layer specification.

Data conformance requires defining grain, identity, key strategy, survivorship rules for deduplication, and boundary data quality rules. Standardization and normalization rules are also specified to ensure silver entity and event datasets remain consistent and trusted.

Yes, designing silver requires an existing Phase 09 bronze layer specification and handoff. If these bronze inputs are unavailable, you must explicitly accept the associated risks before proceeding with silver layer design and phase handoff.

No, silver layer design enforces strict guardrails against designing gold marts, semantic models, orchestration, CI/CD, or transformation code. It strictly focuses on silver entity and event datasets to prevent scope creep into downstream architectural layers.

Outputs include the silver layer specification, support plan, evidence pack, artifact revision, Done Gate, and Phase 10 to 11 handoff. These governance-ready artifacts capture explicit HALT-driven decisions to ensure downstream traceability and compliance.
