Data Modelling and Design — Lesson 1: Business Requirements, Subject Areas, Conceptual Models, and Definitions

Learning Objectives

• Explain the architecture, workflow, or business purpose behind stakeholders, decisions, processes, events, and information requirements.
• Apply subject areas, scope boundaries, business objects, and relationships and conceptual entity-relationship models and cardinality in a controlled scenario.
• Validate outcomes and troubleshoot risks involving business glossary, definitions, assumptions, and unresolved questions.

Detailed Topics

• stakeholders, decisions, processes, events, and information requirements
• subject areas, scope boundaries, business objects, and relationships
• conceptual entity-relationship models and cardinality
• business glossary, definitions, assumptions, and unresolved questions

Instructor Demonstration

Demonstrate stakeholders, decisions, processes, events, and information requirements within a customer-and-order platform redesigned to eliminate ambiguity, duplication, inconsistent keys, and reporting gaps, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 1.

Hands-On Exercise

Implement a controlled exercise covering subject areas, scope boundaries, business objects, and relationships and conceptual entity-relationship models and cardinality, then introduce and resolve an exception involving business glossary, definitions, assumptions, and unresolved questions while preserving before-and-after evidence.

1. Confirm the environment, identities, inputs, dependencies, risks, and expected outcome.
2. Complete the course-specific configuration, development, analysis, or process workflow.
3. Capture settings, commands, data, outputs, logs, reports, screenshots, calculations, or test results.
4. Compare the observed result with acceptance criteria and document corrective action.

Scenario Analysis

• Identify the technical or business decision that must be made.
• Compare valid approaches and their security, performance, reliability, cost, compliance, and support trade-offs.
• Define rollback, recovery, ownership, communication, and evidence requirements.

Troubleshooting Guidance

Diagnose issues across stakeholders, decisions, processes, events, and information requirements, subject areas, scope boundaries, business objects, and relationships, conceptual entity-relationship models and cardinality, business glossary, definitions, assumptions, and unresolved questions without making an unverified production change. Separate symptoms from causes, gather evidence, test the smallest reversible correction, rerun validation, and record preventive action.

Validation Checklist

• The requirement, scope, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by course-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Business Requirements, Subject Areas, Conceptual Models, and Definitions in a realistic Data Modelling and Design scenario and validate the result with documented evidence.
