数据库管理员(DBA)的主要责任是确保企业数据对用户可用。他们需要与开发者紧密合作，确保应用程序高效利用数据库资源，并与系统管理员协作，确保物理资源充足且使用效率高。DBA还负责Oracle数据库架构理解、安装、升级、备份策略制定、网络环境配置、数据库对象管理、性能监控和调优等关键任务。

The principal responsibility of a database administrator (DBA) is to make enterprise data available to its users. DBAs must work closely with the developers to ensure that their applications make efficient use of the database, and with system administrators to ensure that physical resources are adequate and used efficiently.

Oracle DBAs are responsible for understanding the Oracle Database architecture and how the database works. DBAs can expect to perform the following tasks:

Installing, upgrading, and patching Oracle Database software
Designing databases, including identifying requirements, creating the logical design (conceptual model), and physical database design
Creating Oracle databases
Developing and testing a backup and recovery strategy, backing up Oracle databases regularly, and recovering them in case of failures
Configuring the network environment to enable clients to connect to databases
Starting up and shutting down the database
Managing storage for the database
Managing users and security
Managing database objects such as tables, indexes, and views
Monitoring and tuning database performance
Investigating, gathering diagnostic data for, and reporting to Oracle Support Services any critical database errors
Evaluating and testing new database features
