in databases what is a dba
The DBA has many different responsibilities, but the overall goal of the DBA is to keep the server up at all times and to provide users with access to the required information when they need it. The DBA makes sure that the database is protected and that any chance of data loss is minimized. A DBA can be a programmer who, by default or by volunteering, took over the responsibility of maintaining a SQL Server during project development and enjoyed the job so much that he switched.
