Types of Oracle Database Users : Database Administrators (1)

Each database requires at least one database administrator (DBA). An Oracle Database
system can be large and can have many users. Therefore, database administration is
sometimes not a one-person job, but a job for a group of DBAs who share
responsibility.
A database administrator＇s responsibilities can include the following tasks:
■ Installing and upgrading the Oracle Database server and application tools
■ Allocating system storage and planning future storage requirements for the
database system
■ Creating primary database storage structures (tablespaces) after application
developers have designed an application
■ Creating primary objects (tables, views, indexes) once application developers have
designed an application
■ Modifying the database structure, as necessary, from information given by
application developers
■ Enrolling users and maintaining system security
■ Ensuring compliance with Oracle license agreements
■ Controlling and monitoring user access to the database
■ Monitoring and optimizing the performance of the database
■ Planning for backup and recovery of database information
■ Maintaining archived data on tape
■ Backing up and restoring the database
■ Contacting Oracle for technical support
