The types of users and their roles and responsibilities depend on the database site. A small site can have one database administrator who administers the database for application developers and users. A very large site can find it necessary to divide the duties of a database administrator among several people and among several areas of specialization.
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.
以上是Oracle® Database Administrator's Guide 的两段话
