Questions 1–10 of 10

1. What is Canonical Data Modelling?
Question 1A. The practice of defining a standard, enterprise-wide representation of core data entities so all systems can exchange information consistentlyB. The practice of defining reasoning rules for machinesC. The practice of arranging concepts into hierarchiesD. The practice of tuning a database for performanceE. The practice of writing natural-language fact sentences
2. What does the term canonical refer to?
Question 2A. A historical or archived formB. A compressed formC. A standard or accepted formD. An encrypted formE. A temporary form
3. What problem arises with point-to-point integration as an enterprise grows?
Question 3A. Systems cannot be connected at allB. Data becomes automatically standardisedC. Only one system can send dataD. The number of integrations expands rapidly, creating tight coupling, duplicated transformation logic and high maintenance overheadE. Storage costs fall too quickly
4. In a canonical approach, what does each system translate to and from?
Question 4A. Every other system's proprietary formatB. The data warehouse onlyC. The canonical structure onlyD. A spreadsheetE. The ERP system's format
5. If an ERP integrated with twenty applications is replaced under a canonical model, what must be updated?
Question 5A. All twenty application mappingsB. The canonical model itselfC. Every downstream databaseD. Only the ERP-to-canonical mappingE. Nothing needs updating
6. Which of the following is NOT listed as a standardised element of a canonical Loan Application?
Question 6A. Customer IdentifierB. Application IdentifierC. Application DateD. Loan AmountE. Branch Manager Name
7. How does Canonical Data Modelling differ from ontology modelling?
Question 7A. Canonical modelling focuses on practical interoperability and exchange; ontology modelling focuses on meaning, classification and reasoningB. Canonical modelling enables inference; ontology modelling does notC. They are the same techniqueD. Ontology modelling is used only at integration layersE. Canonical modelling defines hierarchies of concepts
8. Where are canonical models typically implemented?
Question 8A. In end-user spreadsheetsB. In business glossaries onlyC. In process diagramsD. In physical storage indexesE. At integration layers such as APIs, service buses, integration hubs or event-driven architectures
9. How many mappings does a point-to-point approach require, as expressed in the integration comparison?
Question 9A. n mappingsB. n × (n-1) mappingsC. 2n mappingsD. n/2 mappingsE. One mapping
10. What kind of integration pattern does Canonical Modelling replace, and with what?
Question 10A. It replaces one-to-one with many-to-manyB. It replaces many-to-many integrations with one-to-manyC. It replaces one-to-many with many-to-manyD. It removes integration altogetherE. It replaces batch with real-time
