Who is a DBA? Most of the people who are interested in IT careers often talk about becoming a Database Administrator. There is no surprise as the demand for Database Administrators continues to rise. But while interest is quite high do many really know what being a DBA entails?
A database is a collection of information which is related to a particular function or purpose. In the simplest form, the contact information kept in a file on the system is a database. We will dwell much on databases here but it is also important to understand which drives the demand for DBAs. A key requirement of IT infrastructure is secure and timely access to and storage of vital data. The most reliable, time-tested method of storing electronic data is inside a database.
Databases are needed by organizations that store and use information, irrespective of location or industry. And in today's knowledge-driven economy useful and timely access to information makes the difference. Why use databases is like asking why electricity is useful. Is there any industry or business that doesn't depend on information? The aim of databases is to aid the generation and the exploitation of knowledge in a reliable and cost-effective manner.
How would banks survive without databases on customers and financial transactions? E-business sites use databases to track orders and inventory. Telecom operators can't do without databases if they must keep track of accounting and subscriber information. Airlines, airports depend on databases.
The most popular database products are from Oracle, Microsoft, IBM and MySQL . Oracle is the market leader in the database market followed by Microsoft SQL Server. And from the open source scene, MySQL is making impressive impact in the database world.
DBAs are also regarded as "those professionals who have organized information in a meaningful way so that it can be maintained easily, retrieved and updated". Database Administrators ensure that data produces and delivers real business value. The role of the database administrator is important in an organization.
