Database Administrators (DBAs) are responsible for the design, implementation, support and maintenance of computerized databases in today’s organizations. The role also includes architecture, building and scaling databases for future data growth and capacity. They are also responsible for security, performance and availability of data to users and customers. .
All the above tasks are performed with the help of a Database Management System (DBMS) and the leading and most widely used DBMS across the world today are the Oracle Database, Microsoft SQL Server, MySQL database etc. Out of the three DBMS technologies, Oracle Database is the most popular and widely used database in the world today.
