Power BI Developer — Lesson 2: Data Modeling and DAX Development

Learning Objectives

• Create fact and dimension tables with clear granularity
• Configure relationships, date tables, hierarchies, and model properties
• Develop measures using filter context, variables, iterators, and time intelligence

Detailed Topics

• Create fact and dimension tables with clear granularity: Create fact and dimension tables with clear granularity
• Configure relationships: Configure relationships, date tables, hierarchies, and model properties
• Develop measures using filter context: Develop measures using filter context, variables, iterators, and time intelligence

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Create a star-schema model and a tested set of business measures.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, permissions, data, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, support ownership, and user or business impact.

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Data Modeling and DAX Development in a realistic scenario and validate the result with documented evidence.
