过程DBA负责审查和管理数据库的过程对象。过程DBA专门开发和支持关系数据库控制和执行的过程逻辑：存储过程、触发器及用户自定义的函数（UDFs）。过程DBA确保过程逻辑是按规划进行的、可实施的、经过测试的、可共享的（可重用的）。

A procedural DBA specializes in the development and support of procedural DBMS logic. This role typically involves writing and maintaining stored procedures, triggers, and other database programming constructs that are used to implement business logic directly within the database. Therefore, the correct answer is:

C: Development / support of procedural DBMS logic. 程序 DBMS 逻辑的开发/支持

**Professional Analysis:**

1. **Understanding Procedural DBMS Logic:**
- Procedural DBMS logic refers to the programming logic that is executed within the database environment. This includes stored procedures, functions, and triggers, which are written in procedural languages like PL/SQL for Oracle or T-SQL for SQL Server.
- These constructs allow for complex operations to be performed directly on the database server, which can improve performance by reducing the amount of data transferred between the server and client applications.

2. **Role of a Procedural DBA:**
- A procedural DBA focuses on ensuring that the procedural logic within the database is efficient, robust, and maintains data integrity.
- They are responsible for writing new procedures, optimizing existing ones, and troubleshooting issues related to procedural logic.
- This role often requires a deep understanding of both database architecture and the specific business processes that the logic is meant to support.

3. **Difference from Other DBA Roles:**
- Unlike a systems DBA who might focus on setting and tuning DBMS system parameters (option A) or ensuring database availability in accordance with SLAs (option B), a procedural DBA is more involved in the logical layer of the database.
- While a development DBA might focus on the broader scope of developing and supporting database applications (option D), a procedural DBA hones in specifically on the procedural aspects within the database environment.

In conclusion, a procedural DBA's expertise lies in crafting and maintaining the procedural components of a database system, which are crucial for implementing complex business logic and ensuring efficient database operations.
