The Metrics Layer: Single Source of Truth for Definitions

April 4, 2026 • 6 min read • Data

← Back to Blog

Revenue in BI = $10M. Revenue in the exec dashboard = $11M. The metrics layer exists to end this. In 2026 every mature data stack has one.

What It Is

Centralized metric definitions. 'Revenue' defined once. BI, notebooks, embedded analytics all query the same definition.

Options

dbt Semantic Layer, Cube, Metriql. Native in some BI tools.

Integration

SQL-like API. Consumers do not need to know source table structure; they query metrics.

Adoption

Socialize definitions. Migrate dashboards one by one. Deprecate direct-table queries.

Who This Is For

  • Data and analytics engineering leaders
  • CTOs modernizing their data stack
  • Teams making decisions off data they can't yet trust

Common Mistakes

  • Buying the stack before defining what decisions it supports
  • Ignoring data contracts until pipelines break at 3am
  • Assuming dashboards equal data quality

Business Impact

  • Single source of truth for every business metric
  • Analytics velocity that matches product velocity
  • Data systems that power AI without rewrites

Frequently Asked Questions

Cube or dbt?

dbt for dbt-native orgs. Cube for broader query API needs.

Headless BI?

Related concept. Metrics layer as a service with no native UI.

Migration cost?

Real. Worth it. Discrepancies cost more than migration.
