Analytics & BI

Data Modeling

Structure data for decisions, not just queries

Good data modeling is invisible — bad modeling shows up in every dashboard, every metric inconsistency, every late-night re-run. We design data models that are correct, performant, and built to outlast individual analysts.

What we deliver

Data Modeling capabilities, end to end

Dimensional modeling

Kimball-style dimensional models for analytics workloads — facts, dimensions, and conformed grain.

  • Star and snowflake schema design
  • Slowly changing dimension strategies (SCD Type 1/2/6)
  • Conformed dimensions across business domains
  • Aggregate and materialized-view strategy

Data vault and hybrid modeling

Where source volatility or audit needs demand it — Data Vault 2.0 patterns and hybrid approaches.

  • Hub, link, and satellite design
  • Business and raw vault separation
  • Historization and audit patterns
  • Vault-to-mart conversion patterns

Semantic and metric layer

A single, versioned definition of every business metric — accessible to BI tools, AI agents, and notebooks.

  • dbt Semantic Layer or Cube implementations
  • Metric ownership and review workflow
  • Metric tests and regression protection
  • Self-service exposure

Modeling reviews and refactoring

Audit and refactor existing models that have drifted into something nobody wants to touch.

  • Model audit: redundancy, ambiguity, performance
  • Refactor plan with backwards-compatibility
  • Documentation and lineage capture
  • Training and handover
