Which activity does NOT fall under the responsibility of a Database Administrator (DBA)?

A Database Administrator (DBA) primarily focuses on the technical aspects of database management, ensuring that databases run efficiently and securely. The responsibilities of a DBA typically include setting up database structures, which involves designing and implementing the architecture of databases to meet various organizational needs. Evaluating database performance is also a core responsibility, as it involves monitoring and optimizing the performance of databases to ensure they operate within expected parameters.

Additionally, developing recovery procedures is crucial for data integrity and security. This involves planning for data backup and restoration in the event of a failure, which is also a critical function that ensures the continuity of data services.

In contrast, conducting user training is generally not seen as a primary responsibility of a DBA. While a DBA may provide some level of support or guidance about database systems, formal user training is typically handled by other roles or departments within an organization, such as IT support teams or dedicated training personnel. The focus of a DBA is more on the technical management of the database rather than on training users.
