Develop Fusion Applications using Visual Builder Studio LVC — Lesson 3: Business Objects, REST Services, Service Connections, Data Binding, and Logic

Learning Objectives

• Interpret prerequisites, ownership, dependencies, and failure conditions for business objects, rest services, service connections, data binding, and logic.
• Perform the course-specific workflow while recording evidence at each material checkpoint.
• Prove the solution against security, control, reliability, performance, and support criteria.

Detailed Topics

• Business Objects
• REST Services
• Service Connections
• Data Binding
• Logic
• ownership, prerequisites, data, and acceptance criteria for business objects, rest services, service connections, data binding, and logic
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate business objects, rest services, service connections, data binding, and logic within a Fusion application extension developed with Visual Builder Studio, integrated with REST services, versioned, tested, and deployed safely. Use representative data and capture service responses, data-binding output so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled Develop Fusion Applications using Visual Builder Studio LVC activity focused on business objects, rest services, service connections, data binding, and logic. Introduce a realistic case of insecure service calls, isolate its cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Establish current state, desired state, constraints, and acceptable service impact.
• Compare alternative implementation or diagnostic approaches and their rollback consequences.
• Document the decision, evidence, exception, corrective action, and measurable improvement target.

Troubleshooting Guidance

When business objects, rest services, service connections, data binding, and logic does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant service responses, data-binding output before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create insecure service calls elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by service responses, data-binding output.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Business Objects, REST Services, Service Connections, Data Binding, and Logic in a realistic Develop Fusion Applications using Visual Builder Studio LVC situation and defend the result with course-specific evidence.
