A database administrator (DBA) is an IT professional responsible for the installation, configuration, upgrading, administration, monitoring, maintenance, and security of databases in an organization.[1]

The role includes the development and design of database strategies, system monitoring and improving database performance and capacity, and planning for future expansion requirements. They may also plan, co-ordinate and implement security measures to safeguard the database.[2]


List of skills required to become database administrators are:[3][4][5]

Some employers require a bachelor's degree or higher in computer science, information technology, engineering or related field to perform job duties as a database administrator.


Employing organizations may require that a database administrator have a certification for the particular RDBMS being used.[2]

For example:

  • IBM Certified Advanced Database Administrator - DB2 10.1 for Linux, Unix and Windows[6]
  • IBM Certified Database Administrator - DB2 10.1 for Linux, Unix, and Windows[7]
  • Oracle Database 11g Administrator Certified Professional[8]
  • MCSA SQL Server 2012[9]


A database administrator's responsibilities can include the following tasks:[10]

  • Installing and upgrading the database server and application tools
  • Allocating system storage and planning future storage requirements for the database system
  • Modifying the database structure, as necessary, from information given by application developers
  • Enrolling users and maintaining system security
  • Ensuring compliance with database vendor license agreement
  • Controlling and monitoring user access to the database
  • Monitoring and optimizing the performance of the database

Job titles[edit]

DBAs are also known[by whom?] by the titles database coordinator or database programmer, although a database programmer requires more advanced skills in SQL programming than a DBA may have, and database programmers may not have and do not require the skills of database administration, backing up, restoring, monitoring or tuning to do their job well.[2]

The role integrates closely with the other jobs of database analyst, database modeller, programmer analyst, and systems manager.[2]

Some organizations[clarification needed] have a hierarchical system of database administrators, generally:[11]

  • Junior DBAs
  • Mid-level DBAs
  • Senior DBAs
  • DBA consultants
  • Manager or director of database administration/information technology
