Every business organization today uses Database Management Systems to effectively store, manage and manipulate data, which is crucial for the smooth functioning of business. So the role of a database administrator is important, as he designs, configures, and maintains databases. He is also responsible for the secure collection, transmission and storage of data, as any loophole may seriously affect the business operations of the organization. Taking into consideration the significance of the role of DBAs, it is no surprise that the demand for them has been rising over the years.

To become DBA certified by Oracle, the leading developers of Relational Database Management Systems, you need to take one or two exams depending upon your skills and experience.
