OG0-093 · Question #257
Which one of the following is NOT an objective for Phase C, Data Architecture?
The correct answer is D. Defining data entities that are normalized to minimize update anomalies. Defining data entities that are normalized to minimize update anomalies is a detailed database design technique and not a primary objective of TOGAF ADM Phase C, Data Architecture.

Why each option
Defining data entities that are normalized to minimize update anomalies is a detailed database design technique and not a primary objective of TOGAF ADM Phase C, Data Architecture.
Defining an architecture that can be understood by the stakeholders is a general quality objective for all TOGAF architectural phases, including Data Architecture, to ensure communication and buy-in.
Defining an architecture that is complete and consistent is a fundamental quality objective for any architecture developed in TOGAF, ensuring its comprehensiveness and internal harmony.
Defining an architecture that is stable is an important objective in TOGAF Phase C, meaning the data architecture should be robust and adaptable to future changes with minimal disruption.
Normalization is a detailed database design activity aimed at optimizing data structures for integrity and efficiency, typically performed during detailed system design or implementation rather than during the high-level enterprise data architecture definition in TOGAF Phase C. Phase C focuses on defining logical and physical data architectures at an architectural level.
Defining data entities relevant to the enterprise is a core objective of Phase C, as it involves identifying and modeling the key data concepts essential to the business operations.
