Semantic Layer Design (DAX, TMDL)

Table of Contents

🧩 What This Covers
#

I design semantic layers using DAX and TMDL that turn raw tables into understandable, business-aligned models. These models support consistent analysis, clear metric definitions, and high-performance reporting across teams and tools.

🛠 Common Scenarios
#

  • You need consistent metrics across multiple reports or teams
  • Business logic is buried in report-level formulas or ad hoc queries
  • Your model feels slow, redundant, or hard to manage
  • Teams interpret KPIs differently due to inconsistent definitions
  • You’re moving toward a semantic layer strategy (e.g. Power BI, Fabric)

📌 What I Focus On
#

  • Modeling explicit, reusable business logic
  • Organizing measures, dimensions, and tables with clarity and structure
  • Writing efficient, readable DAX for performance and maintainability
  • Using TMDL to standardize model structure and simplify version control
  • Enabling trust, reuse, and scale across the reporting environment

🚀 Outcomes You Can Expect
#

  • Shared understanding of key metrics across teams
  • Faster, more consistent reporting development
  • Models that are easier to validate, extend, and reuse
  • Business users and analysts working from the same reliable definitions
