Database administration: which of the following is NOT a primary responsibility of a database administrator (DBA)?

Introduction / Context:
A database administrator (DBA) governs the organization’s data resources: schema design, security, performance, backup/recovery, and metadata management. While DBAs collaborate across teams, some activities are central to the role, and others are more properly owned by systems or business analysts. Distinguishing these boundaries helps clarify accountability in projects.

Given Data / Assumptions:

• We are comparing core DBA functions with adjacent roles.
• “Designing the database” and “data dictionary” creation are classic DBA deliverables.
• DBAs often advise programmers on SQL, indexing, and standards, but do not own application analysis.

Concept / Approach:
DBA core: logical/physical schema design, security policies, performance tuning, capacity planning, backup and recovery, and stewardship of metadata (data dictionary/catalog). Application systems analysis—eliciting business requirements, modeling processes, designing UI/UX—falls under systems/business analysis, not the DBA’s primary mandate, though collaboration is common.

Step-by-Step Solution:

Verification / Alternative check:
Role descriptions consistently separate DBA (data platform) from systems analyst (application requirements), supporting the chosen exception.

Why Other Options Are Wrong:

• Advising programmers: common DBA collaboration for query tuning and standards.
• Designing the database: central DBA task.
• Developing the data dictionary: typical DBA/DA responsibility.
• None: incorrect because one clear exception exists.

Common Pitfalls:
Assuming DBAs own all things “data” including application logic; their mandate centers on data platforms and governance rather than end-to-end application analysis.

Final Answer:
analyzing application systems
