database administrator

in any organization where many people use the same resources, there is a need for a chief administrator to oversee and manage these resources. in a database environment, the primary resource is the database itself, and the secondary resource is the dbms and related software. administering these resources is the responsibility of the database administrator (DBA). the DBA is responsible for authorizing access to the database, coordinating and monitoring its use, and acquiring software and hardware resources as needed. the DBA is accountable for problems such as security breaches and poor system response time. in large organizations, the DBA is assisted by a staff that carries out these functions.
