                  问题描述

                  Oracle 中的视图和物化视图有什么区别?

                  What is the difference between Views and Materialized Views in Oracle?

                  推荐答案

                  物化视图基于磁盘,并根据查询定义定期更新.

                  Materialized views are disk based and are updated periodically based upon the query definition.

                  视图只是虚拟的,每次访问时都会运行查询定义.

                  Views are virtual only and run the query definition each time they are accessed.
