DBMS utilities: identify the non-responsibility In database management systems, the utilities component provides housekeeping and support tools. Which of the following is NOT typically a responsibility of DBMS utilities?

Introduction / Context:
DBMS utilities are support programs that help maintain, protect, and tune a database. They differ from core DBMS engines (query processing, transaction management) and from design-time activities (data modeling and schema design). Knowing what falls inside “utilities” clarifies roles between database designers, DBAs, and system tools.

Given Data / Assumptions:

• The question focuses on the utilities component of DBMS software.
• Typical utilities include backup/restore, reorganization, performance monitoring, export/import, integrity checks, and data dictionary maintenance.
• Physical/logical design creation is usually an analysis/design activity, not an operational utility task.

Concept / Approach:
Utilities deal with ongoing operations and maintenance. By contrast, creating physical and logical designs stems from conceptual modeling (entity-relationship analysis), normalization, and physical layout decisions (indexes, partitions), generally performed by data architects/DBAs using design tools, not by runtime utilities.

Step-by-Step Solution:

Verification / Alternative check:
Vendor documentation groups utilities under maintenance tasks (e.g., ANALYZE/STATISTICS, REORG, BACKUP, RESTORE, MONITOR), while data design is documented under modeling tools and DBA planning guides.

Why Other Options Are Wrong:

• Removing flagged records for deletion: classic reorganization/cleanup utility.
• Creating/maintaining the data dictionary: dictionary utilities synchronize metadata.
• Monitoring performance: supplied monitors/profile tools are standard utilities.

Common Pitfalls:
Assuming “utilities” means “anything a DBA touches.” Utilities operate the system; they do not create the conceptual/physical schema from scratch.

Final Answer:
creating the physical and logical designs
