Data Analysis with Multidimensional Modelling — Lesson 4: Processing, Performance, Deployment and Operations

Learning Objectives

• Process models, manage partitions, deploy changes, validate totals, monitor failures, and troubleshoot data issues
• Tune aggregations, storage modes, queries, caches, processing windows, capacity, documentation, and support
• Validate processing, performance, deployment and operations decisions with documented requirements, evidence, risk controls, and measurable acceptance criteria

Detailed Topics

• Process models: Process models, manage partitions, deploy changes, validate totals, monitor failures, and troubleshoot data issues
• Tune aggregations: Tune aggregations, storage modes, queries, caches, processing windows, capacity, documentation, and support
• Validate processing: Validate processing, performance, deployment and operations decisions with documented requirements, evidence, risk controls, and measurable acceptance criteria

Guided Demonstration

1. Review the requirement, users, data, dependencies, permissions, risks, and expected result.
2. Demonstrate the relevant configuration, development, analysis, administration, testing, or operational workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, test results, and other useful evidence.
4. Compare the observed result with acceptance criteria and explain any corrective action.

Hands-On Activity

Complete an end-to-end review, troubleshoot defects, document handoff controls, and prioritize improvements.

• Document assumptions, prerequisites, and the planned sequence before starting.
• Complete the activity and preserve evidence of normal, boundary, and failure behavior.
• Record issues, corrective actions, reusable notes, and the next improvement priority.

Scenario Analysis

• Identify the business or technical decision that must be made.
• Compare valid implementation approaches and their trade-offs.
• Consider security, privacy, accessibility, performance, support, and operational impact.

Troubleshooting Focus

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

Validation Checklist

• The requirement, scope, inputs, and expected outcome are clear.
• The selected design or configuration is documented and follows approved standards.
• Normal, boundary, failure, security, accessibility, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Processing, Performance, Deployment and Operations in a realistic scenario and validate the result with documented evidence.
