Key roles of database administrator

The roles of a DBA vary from organization to organization. But the following list shows the primary activities that many DBAs are charged with:

• Back up and recover the database.
• Install and configure Oracle software.
• Create new databases.
• Design the database schema and create any necessary database objects.
• Formulate optimal application SQL.
• Ensure database security is implemented to safeguard the data.
• Work closely with application developers and system administrators to ensure all database needs are being met.
• Apply patches or upgrades to the database as needed.

The list above may not be complete for your organization, but it is a good start.
