Power BI Developer — Lesson 1: Data Acquisition and Power Query Engineering

Learning Objectives

• Connect to files, databases, services, and structured business sources
• Profile, clean, transform, combine, and validate data in Power Query
• Design reusable parameters, queries, and data-preparation standards

Detailed Topics

• Connect to files: Connect to files, databases, services, and structured business sources
• Profile: Profile, clean, transform, combine, and validate data in Power Query
• Design reusable parameters: Design reusable parameters, queries, and data-preparation standards

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

Build and validate a reusable Power Query pipeline for a multi-source reporting scenario.

• 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 Acquisition and Power Query Engineering in a realistic scenario and validate the result with documented evidence.
