Programming in VB.NET — Lesson 4: Database Integration, Testing, and Delivery

Learning Objectives

• Connect to relational databases and execute parameterized operations
• Validate transactions, data mapping, errors, and resource management
• Apply testing, documentation, security, packaging, deployment, and review

Detailed Topics

• Connect to relational databases and execute parameterized operations: Connect to relational databases and execute parameterized operations
• Validate transactions: Validate transactions, data mapping, errors, and resource management
• Apply testing: Apply testing, documentation, security, packaging, deployment, and review

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

Complete a data-enabled VB.NET application and a release-readiness checklist.

• 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 Database Integration, Testing, and Delivery in a realistic scenario and validate the result with documented evidence.
