Extent to which the administration of a database is automated dictates the skills required to manage databases. As automation increases, the organization requires highly skilled workers to create and manage the automation and a group of lower skilled line DBAs to execute the automation.
Candidates with multiple years of experience are usually preferred by the companies as database administration work is complex, repetitive, time-consuming and requires significant training besides the fact that databases hold valuable and mission-critical data.
The DBA must have the skills to recover the database to a given point in time to prevent a loss of data, in cases ranging from simple failure to a full catastrophic failure. A highly skilled DBA can spend a few minutes or exceedingly long hours to get the database back to the operational point.
Database administration tools
- The tools that come up with the DBMS software to help DBAs manage the DBMS are called native tools. Example: Microsoft SQL Server comes with SQL Server Enterprise Manager and Oracle has tools such as SQL*Plus and Oracle Enterprise Manager/Grid Control.
- To monitor the DBMS and help DBAs carry out certain functions inside the database more easily, third parties such as BMC, Quest Software,Embarcadero Technologies, EMS Database Management Solutions and SQL Maestro Group offer GUI tools.
- Another kind of database software exists to manage the provisioning of new databases and the management of existing databases and their related resources.
