通过提高可管理性、性能和可用性，分区可以为各种应用程序带来巨大的好处。一般来说，分区可以极大地提高某些查询的性能以及维护操作。此外，使用“分层归档”分区，分区可以大大降低数据的总拥有成本。将旧的相关信息在线保存在低成本存储设备上的方法。对于大型环境中的信息生命周期管理，Oracle Partitioning 提供了一种高效、简单但非常强大的方法。分区使数据库设计人员和管理员能够解决尖端应用程序带来的一些挑战。分区是构建千兆字节数据系统或超高可用性系统的关键工具。
(By improving manageability, performance, and availability, partitioning can bring significant benefits to a variety of applications. Generally speaking, partitioning can greatly improve the performance of some queries and maintenance operations. In addition, with "tiered archive" zoning, zoning can significantly reduce the total cost of ownership of data. A method of keeping old relevant information online on low-cost storage devices. Oracle partitioning provides an efficient, simple, but powerful approach to information lifecycle management in large environments.
Partitioning enables database designers and administrators to address some of the challenges posed by cutting-edge applications. Partitioning is a key tool for building Gigabit data systems or ultra-high availability systems.)
