dbt-modeling

What I do

• Structure dbt models by layer.
• Recommend source declarations.
• Standardize naming and typing in staging.
• Keep marts focused on analytical consumption.

Layer guidance

• sources declares raw objects and tests expectations.
• staging standardizes structure and names.
• marts implements business-ready aggregations and dimensions.

Guardrails

• Prefer explicit selected columns.
• Keep staging models close to source semantics.
• Push metric logic to marts unless a shared intermediate model is justified.
