Data Mastery with SSAS and MS SQL Server 2022 — Lesson 3: Tabular Models, DAX, Security, and Performance

Learning Objectives

• Create tabular models, relationships, calculated columns, measures, and DAX expressions
• Apply roles, row-level security, perspectives, and controlled access to analytical data
• Tune storage, processing, partitions, calculations, and query performance

Detailed Topics

• Create tabular models: Create tabular models, relationships, calculated columns, measures, and DAX expressions
• Apply roles: Apply roles, row-level security, perspectives, and controlled access to analytical data
• Tune storage: Tune storage, processing, partitions, calculations, and query performance

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

Develop a secured tabular model and improve one slow analytical workload.

• 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 Tabular Models, DAX, Security, and Performance in a realistic scenario and validate the result with documented evidence.
