✍️ Sample CDP Questions & Answers
1. Which messaging standard is most commonly used to ensure interoperability between healthcare information systems?
HL7 (Health Level 7) is the dominant standard for exchanging clinical and administrative data between healthcare applications and systems.
2. What is the purpose of a Business Glossary in data governance?
A Business Glossary provides a common vocabulary with standardized definitions to ensure consistent communication across business units.
3. What does the integration pattern known as 'scatter-gather' accomplish?
The scatter-gather pattern fans out a single request to multiple services concurrently (scatter), then waits for and combines all responses into a single aggregated result (gather).
4. What is database normalization's Third Normal Form (3NF) requirement?
3NF requires that non-key attributes depend only on the primary key (not on other non-key attributes), eliminating transitive dependencies that cause update anomalies.
5. What is 'data provenance'?
Data provenance documents the origin, custody, and transformations of data throughout its lifecycle to ensure trustworthiness and traceability.
6. In data interoperability, what does 'semantic interoperability' specifically ensure?
Semantic interoperability ensures that when data is exchanged between systems, both systems interpret the meaning, context, and business definitions of that data in the same consistent way.
