In order to know about the profession of a database administrator, it becomes imperative to understand what a database is. A database is an accumulation of information systematized in such a manner that through a program on the computer, any desired single data can be quickly selected.

It is an electronic filing system. Files, records and fields are the traditional methods of organizing database. A single part of information is field and one complete set of fields is called a record.

In database design it is alternatively called Hypertext. Any object, whether it is a picture, a film or a piece of text can be connected (linked) to any other object. Information from a database can be accessed through Database Management System (DBMS). DBMS is a group of programs through which you can enter, select and organize data in a database.



The important role of a Database Administrator is to supervise the installation and continuing operations of a software system which has been designed for use by various users. Database Administrators have to install new databases, create backup records of information contained in databases and upgrade the system and make available new releases from time to time. Today with the expansion of the role of Database Administrator, he is also called upon to take up the functions which are generally associated with Database Designer or Analyst like basic designing and customization of the fields or functions. He should also be competent enough to write complex SQL (Structured Query Language).

Application DBA is required by organizations that have bought software for third party applications like Enterprise Resource Planning and Customer Relationship Management including SAP, PeopleSoft, Siebel and Oracle Applications. Data designing, maintenance, generation of language of data definition, tuning and writing SQL coding etc., are the functions of Development Database Administrator.

To help Database Administrators to manage the system, DBMS software is provided with certain native tools.

Besides this, other parties like SQL Maestro Group, EMS Database Management Solutions, Embarcadero Technologies, BMC and Quest Software provide GUI tools. All these tools help DBAs to perform DBMS functions in a more convenient manner.
