About The Database Administrator’s (DBA) Job Description
I am a final year BE student interested in developing a career in DBA
Can you tell me the future prospects for DBA jobs and do i need to have a good knowledge of programming like C,C++,java,.net etc to be a DBA?
And I have also heard that getting jobs in DBA as freshers is very tough and companies don’t prefer DBA as freshers.
The Duties, Roles And Responsibilities of Database Administrators (DBAs)
The Database Administrator (DBA)’s job comes with a lot of responsibility and because of that, a lot of experience is usually required for the job.
This is the reason why Database Administrators tend to be seasoned database professionals and not entry level database professionals.
With that in mind, your first goal should be to learn database development first and then get a job where you can work your way up to becoming a DBA by first proving your competency as a database developer first.
Does A DBA Need To Know Scripting Languages?
DBAs are not computer programmers so they do not need to master every facet of programming with C/C++, C#, Java, .NET, etc.
However DBAs also need to write scripts for database maintenance jobs in a specific programming language.
For example, DBAs importing data into a SQL Server database may need to know enough of the Visual Basic scripting language (VBScript) to write some of the Extraction, Transform and Load (ETL) or Data Transformation Services (DTS) tasks required for the Extraction, Transformation or Loading (ETL) process.
Does A DBA Need To Know SQL Programming?
Though DBAs are not required to master computer programming, the normal day to day DBA duties may involve extensive programming in SQL.
For example, a DBA may have to write fairly extensive programming solutions in the SQL Language as part of stored procedures or some other database script.
It’s important to note that each relational database platform has its own native programming language (T-SQL, PL/SQL, Access SQL, etc.)
Introducing The DBA’s Job Description
Here is a quick overview of the database administrator’s (DBA) job description.
The database administrator or DBA is responsible for maintaining the database, applying the patches and upgrading the database.

How To Become A Database Administrator?
The first step in becoming a database administrator is to learn SQL Query Writing, master relational database design and development and study advanced sql topics.
Database Administrator’s tend to be highly skilled database developers and are usually promoted from within. What that means is that in all likelihood, you would start out as a database developer, gain a lot of experience and then move up the ranks or get promoted to a database administrator (DBA).
