Scope of the database administration (DBA) function Which task properly belongs to database administration?

Introduction / Context:
The DBA role focuses on the database environment: architecture, security, performance, backup/recovery, and how applications access data. Distinguishing DBA responsibilities from those of application developers and IT operations ensures clear ownership and smoother projects.

Given Data / Assumptions:

• Application programming belongs to software development teams.
• Computer operations management (e.g., batch scheduling, general system ops) belongs to IT operations.
• DBA responsibilities include planning how applications will access and secure data.

Concept / Approach:
Database access planning includes designing roles and privileges, defining connection patterns, planning indexes/partitions to meet access paths, and coordinating with developers to align SQL and schema. While DBAs may collaborate with dev and ops, the core ownership of access planning lies with DBA.

Step-by-Step Solution:

Identify DBA core: data modeling support, security, performance, capacity, backup/recovery, access methods.Contrast with application coding (dev) and overall ops management (IT operations).Select the task squarely in DBA scope: database access planning.Confirm that other options are outside primary DBA responsibility.

Verification / Alternative check:
Standard DBA job descriptions list access planning and security as primary tasks, while programming and general IT operations are separate competencies.

Why Other Options Are Wrong:
Application programming: developers own code authoring and testing.

Computer operations management: run books, servers, and generic ops tasks are outside DBA scope.

All of the above/None: do not match typical role boundaries.

Common Pitfalls:
Assuming DBAs write application code; they might write scripts or stored procedures, but “application programming” is broader and not primarily a DBA function.

Final Answer:
database access planning
