Who is a Database Administrator?

Data has become the modern treasure companies must protect and cherish with data so readily accessible in this age of apps, tablets, and social media. Database managers are counted on as the guardians of this treasure rather than anything else, enforcing security measures to ensure that confidential information does not fall into the hands of unruly pirates while also maintaining the databases that help store and coordinate it.

In short, database administrators-DBAs-set up databases according to the needs of an organization and ensure that they run efficiently. As required, they will also fine-tune, update, and test changes to the databases. In many of today's IT divisions, and by extension, their organizations in general, the DBA is a critically important feature.


Technical Requirements

Basic requirements of a Database Administrator include prerequisite knowledge of Structured Query Language(SQL), Procedural Language(PL)/SQL, Unix, Relational Database Management System(RDBMS), and Java. A broad range of sub-specializations for the position of a database administrator is also available. 

There are also database managers who, first of all, build and construct databases. They typically work as part of a team, often in a software development company that is more specialized. They are likely to collaborate with business experts and others closely familiar with banking operations to develop the roles and modules of the different applications. This is to ensure that the database structure generates and represents all bank functions (loans, cash transfers, electronic payments, ATM management, etc.).

The 'Performance Database Administrator' or 'Tuning Database Administrator' is another kind of database administrator. This administrator specializes in optimizing the efficiency of different databases and enhancing them. DBAs help ensure that the database is designed to take advantage of the hardware on which it is hosted, physical or virtual. 

'The Application DBA' is a third type of database administrator. This function focuses primarily on incorporating databases into apps that use them. Typically, accessing most databases involves knowledge of a certain kind of query language. The organized query language, or SQL, is the most popular one.
