Self-check

Questions 1–10 of 10

1. What is an Operational Reference Model needed for?
Question 1A. Scheduling batch jobsB. Succeeding with metadata management by describing the structures and relationships of business metadataC. Encrypting data at restD. Replacing the physical data modelE. Measuring network throughput
2. When do Operational Reference Models come into play?
Question 2A. When a single system needs a physical schemaB. When a project needs a communication diagram onlyC. When organisations require an operational layer bridging multiple systems and functions with a common point of reference or shared languageD. When a database needs performance tuningE. When a vendor requires a licence review
3. What distinguishes an Operational Reference Model from an anti-corruption layer or a semantic layer?
Question 3A. It is stored only in memoryB. It applies to a single systemC. It contains no metadataD. It is owned and governed by the organisation's subject matter expertsE. It is maintained by the database vendor
4. What is an Operational Reference Model at its core?
Question 4A. A collection of SQL viewsB. A network diagramC. A list of application serversD. A set of business process flowchartsE. A set of metadata structured with the help of taxonomies and ontologies
5. Which governance approach does an Operational Reference Model follow?
Question 5A. A federated governance approach in which each domain is governed by its subject matter expertsB. Centralised governance by the IT department aloneC. Governance outsourced to the database vendorD. No governance, since the model is self-maintainingE. Governance solely by the finance department
6. In Operational Reference Model governance, what is the role of IT?
Question 6A. Defining taxonomy levels within each domainB. Providing a platform and/or database, plus a framework and interaction points such as integrationsC. Maintaining product-specific metadataD. Defining the ontologies between taxonomiesE. Approving marketing campaigns
7. Which role is responsible in particular for defining the ontologies between different taxonomies?
Question 7A. IT (Platform Owner)B. Subject Matter ExpertsC. Architects (Structure Owner)D. FinanceE. External auditors
8. Which three capabilities must a database have to implement an Operational Reference Model?
Question 8A. Full-text search, geospatial indexing and graph traversalB. Sharding, replication and encryptionC. Column storage, compression and cachingD. Attribute inheritance, taxonomies (classification structures) and ontologies (relations)E. Triggers, stored procedures and views
9. Why is attribute inheritance necessary in an Operational Reference Model?
Question 9A. To speed up query executionB. To reduce storage costsC. To allow vendor-specific extensionsD. To encrypt sensitive attributesE. To ensure attributes are defined and used coherently without creating redundancy and ambiguity
10. Which of the following is NOT a listed benefit of an Operational Reference Model?
Question 10A. Eliminating the need for subject matter expertsB. Reducing time spent on new integrationsC. Enabling metadata quality through ownership by subject matter expertsD. Allowing analysis and simulations across abstraction levelsE. Maintaining a vendor-independent data layer that reduces lock-in
