This includes installing the DBMS and setting up the necessary IT infrastructure to allow applications to interact with the databases. If the organization uses a cloud database, the DBA doesn’t handle the installation but still ensures that the cloud database is properly configured, accessed, and deployed for the organization’s needs.
  • The DBA is also in charge of creating policies and procedures related to how the database management system is managed, secured, maintained, and used. They develop training materials and educate employees on how to use and access the DBMS correctly.

The root cause of this issue can range from data filtering problems to more significant issues in the database code. A skilled DBA can diagnose and fix these problems to ensure the system runs smoothly.

Collaborating with external DBA support can fill any gaps without hiring permanent employees.
