The database administrators (DBAs for short) plan, build and maintain computer systems for information. The type of database they work will depend on your employer - examples include networks of banks account of customer and patient record systems of the hospital.
As a DBA work could range from upgrading a existing database to create a completely new home information.
In a new system would work for an organisation to:

Establish what is the database for use by other systems that are linked with, for example, telephony
· Plan the structure, which shows how to organize the data (the design of the "end"), and how to find and display information (usability 'front end')
• Create a trial version and check the results to solve technical problems, known as bugs
· Fill (fill) the database with new information or transfer existing data into it
· Develop plans to update information, create backups, report bugs and implement security measures.
