The DAMA-DMBOK refers to organizations that treat data as a strategic asset and manage it across its lifecycle as "data-centric." It states: "A data-centric organization values data as an asset, integrates data management into its culture, and manages data through all phases of its lifecycle, from creation to retirement" (DMBOK2, Chapter 3: Data Governance, p. 103).
Options A, B, C, and E are incorrect: C refers to decision-making approaches, while others are not DMBOK terms.
Reference:DAMA-DMBOK2, Chapter 3: Data Governance, Section 2.1, p. 103.

NEW QUESTION # 475
A project scope requires the collection, exchange, and reporting of data from multiple in-house custom systems. Documents gathered include business concepts, existing database schemas, XSDs, and reporting layouts. How many models of each layer of abstraction can be expected?

A. The same number of each of the model types
B. Only 1 conceptual data model, 1 logical data model, and 1 physical data model
C. More XSDs than reporting layouts
D. More conceptual data models than physical data models
E. More physical data models than logical data models, and more logical data models than conceptual data models

Answer: E

Explanation:
In data modeling, there are three levels of abstraction: conceptual, logical, and physical. For a project involving multiple systems, the DAMA-DMBOK explains: "Conceptual models are high-level and few in number, focusing on business entities and relationships. Logical models provide more detail, mapping to multiple systems or schemas, and physical models are the most numerous, tailored to specific database implementations" (DMBOK2, Chapter 5: Data Modeling and Design, p. 177). Since each system may have its own physical schema (physical model) and multiple systems may share logical models, while a single or few conceptual models cover the enterprise, the number of models typically follows: physical > logical > conceptual.
Options A and B don't address modeling layers; D assumes only one model per layer, which is unrealistic for multiple systems; and E reverses the hierarchy. Thus, C is correct.
Reference:DAMA-DMBOK2, Chapter 5: Data Modeling and Design, Section 3.2, p. 177.
