Difficulty: Easy
Correct Answer: Both A and B
Explanation:
Introduction:
Packaged data models are pre-built, industry-specific blueprints that capture best practices and typical entities/relationships. This question evaluates your understanding of how such models impact delivery speed and design quality.
Given Data / Assumptions:
Concept / Approach:
Because packaged models encode recognized patterns, teams accelerate initial modeling, reduce rework, and avoid common design pitfalls. Reuse of proven structures reduces cycle time and bolsters quality through consistency and domain completeness. While security policies improve with better structure, the primary gains are schedule and model quality rather than security alone.
Step-by-Step Solution:
1) Compare the blank-slate approach to leveraging a pre-populated industry model.2) Identify reductions in analysis/design effort, leading to lower cost.3) Recognize quality gains from proven, standardized patterns and terminology.4) Conclude that both faster, cheaper delivery and higher quality are expected outcomes.
Verification / Alternative check:
Case studies from verticals (banking, retail, healthcare) show reduced project risk and improved stakeholder alignment when reusing established reference models.
Why Other Options Are Wrong:
Common Pitfalls:
Underestimating the customization still required; packaged models are starting points, not final deliverables. Teams must localize terminology and constraints to fit specific business rules.
Final Answer:
Both A and B
