A database administrator (DBA) has several responsibilities to ensure the smooth running and efficiency of a database system. Here are some of the key responsibilities:

1. Installing and Upgrading the Database Server: The DBA is responsible for installing the database software and also for any upgrades or patches that need to be applied.

2. Data Modeling and Design: The DBA often helps to design the database structure or schema, which includes defining tables, fields, relationships, indexes, and stored procedures.

3. Monitoring and Optimization: The DBA monitors the database system to ensure it is running efficiently. This can involve tuning, indexing, and sometimes re-designing the database.

4. Data Security: The DBA is responsible for ensuring data is secure from unauthorized access and that there are sufficient backups in case of data loss.

5. Troubleshooting: If there are any issues with the database, it is the DBA's responsibility to diagnose and fix them.

6. User Access and Privileges: The DBA sets up user accounts and determines access levels to protect sensitive information.

7. Data Recovery: In case of a system crash or failure, the DBA is responsible for recovering lost data.

8. Capacity Planning: The DBA needs to plan for future storage needs to ensure that the database can handle growth in data volume.

9. Documentation: The DBA is often responsible for documenting the database system, including all tables, procedures, and interactions.

10. Liaising with Developers: The DBA often works closely with developers to help optimize database queries, improve performance, and assist with data-related coding.
