A database administrator (DBA) is the information technician responsible for directing or performing all activities related to maintaining a successful database environment. A DBA makes sure an organization’s database and its related applications operate functionally and efficiently.
Importance of a DBA
If your organization uses a database management system (DBMS) for mission-critical workloads, it is important to employ one or more database administrators to ensure that applications have ongoing, uninterrupted access to data. Most modern organizations of every size use at least one DBMS, and therefore the need for database administrators is greater today than ever before.
